Linux no wifi device

Ubuntu Documentation

Check that the wireless adapter was recognized

Even though the wireless adapter is connected to the computer, it may not have been recognized as a network device by the computer. In this step, you will check whether the device was recognized properly.

Open a Terminal window, type lshw -C network and press Enter . If this gives an error message, you may need to install the lshw program on your computer.

Look through the information that appeared and find the Wireless interface section. If your wireless adapter was detected properly, you should see something similar (but not identical) to this:

If a wireless device is listed, continue on to the Device Drivers step .

If a wireless device is not listed, the next steps you take will depend on the type of device that you use. Refer to the section below that is relevant to the type of wireless adapter that your computer has ( internal PCI , USB , or PCMCIA ).

PCI (internal) wireless adapter

Internal PCI adapters are the most common, and are found in most laptops made within the past few years. To check if your PCI wireless adapter was recognized:

Open a Terminal, type lspci and press Enter .

Look through the list of devices that is shown and find any that are marked Network controller or Ethernet controller . Several devices may be marked in this way; the one corresponding to your wireless adapter might include words like wireless , WLAN , wifi or 802.11 . Here is an example of what the entry might look like:

If you found your wireless adapter in the list, proceed to the Device Drivers step . If you didn’t find anything related to your wireless adapter, see the instructions below .

USB wireless adapter

Wireless adapters that plug into a USB port on your computer are less common. They can plug directly into a USB port, or may be connected by a USB cable. 3G/mobile broadband adapters look quite similar to wireless (Wi-Fi) adapters, so if you think you have a USB wireless adapter, double-check that it is not actually a 3G adapter. To check if your USB wireless adapter was recognized:

Open a Terminal, type lsusb and press Enter .

Look through the list of devices that is shown and find any that seem to refer to a wireless or network device. The one corresponding to your wireless adapter might include words like wireless , WLAN , wifi or 802.11 . Here is an example of what the entry might look like:

If you found your wireless adapter in the list, proceed to the Device Drivers step . If you didn’t find anything related to your wireless adapter, see the instructions below .

Checking for a PCMCIA device

PCMCIA wireless adapters are typically rectangular cards which slot into the side of your laptop. They are more commonly found in older computers. To check if your PCMCIA adapter was recognized:

Start your computer without the wireless adapter plugged in.

Open a Terminal and type the following, then press Enter :

This will display a list of messages related to your computer’s hardware, and will automatically update if anything to do with your hardware changes.

Insert your wireless adapter into the PCMCIA slot and see what changes in the Terminal window. The changes should include some information about your wireless adapter. Look through them and see if you can identify it.

To stop the command from running in the Terminal, press Ctrl + C . After you have done that, you can close the Terminal if you like.

If you found any information about your wireless adapter, proceed to the Device Drivers step . If you didn’t find anything related to your wireless adapter, see the instructions below .

Wireless adapter was not recognized

If your wireless adapter was not recognized, it might not be working properly or the correct drivers may not be installed for it. How you check to see if there are any drivers you can install will depend on which Linux distribution you are using (like Ubuntu, Arch, Fedora or openSUSE).

To get specific help, look at the support options on your distribution’s website. These might include mailing lists and web chats where you can ask about your wireless adapter, for example.

Нету wlan0

При подключении wifi адаптера не создается интерфейс wlan0. Сам адаптер система видит.

Может он называется по-другому? У меня wlp3s0, например.

Какое-то время адаптер работал нормально на интерфейсе wlan0.

ls /sys/class/net в студию.

ifconfig wlan0 up

Хм. Драйвер на карточку есть?

Какое-то время адаптер работал нормально на интерфейсе wlan0.

Но после очередной перезагрузки работать перестал.

В ходе того ребута ядро обновлял?

Нет, просто чистил логи.

Драйвер карты попробуй загрузить.

Переустановка драйверов не помогла. П.с. Адаптер USB, TP-Link TL-WN821N

если у тебя не два езернета, то может быть один из них.

это не похоже не вывод команды lsusb
должно быть что-то вроде
bus 001 device 001 tut_ima_device
bus 001 device 002 tut_ima_device

В Ubuntu не работает WiFi

Последнее десятилетие особой популярностью пользуется беспроводной Интернет: устанавливается роутер, от которого пользователи любого гаджета спокойно подключаются к мировой сети. И это неудивительно: не надо тратить время на поиск нужного места, где отлично «ловит» Wi-Fi. Однако многие при использования такого Интернета сталкиваются с проблемой: Ubuntu не видит Wi-Fi. Существует множество причин такого исхода и соответствующие им методы исправления сложившейся ситуации.

Возможные причины, по которым Linux не видит WiFi

Когда возникают сомнения: в ubuntu отваливается wi-fi, ubuntu не видит сетевую карту, многие пользователи пытаются найти источники такого состояния самостоятельно. Некоторые обращаются к справочникам и иным информационным источникам, другие спрашивают у друзей, третьи платят лишние средства мастерам.

На самом деле причин того, что ubuntu не видит сеть, debian не видит wi-fi и в ubuntu отключается wi-fi не так уж и много:

1. Ноутбук или какой-либо другой новый гаджет имеет в своей структуре необычную сетевую плату, к которой невозможно установить стандартные для всех моделей драйвера.
2. Неправильная установка операционной системы привело к таким последствиям. Сюда же относятся многочисленные обновления, которые происходят автоматически на многих моделях ноутбуков, смартфонах, планшетах и других гаджетов.
3. На гаджете есть какой-то сбой работы программ, именно он мешает увидеть сеть.
4. Еще одной важной причиной (особенно если пользователь-новичок) такого состояния является неправильная настройка элементов всего оборудования.
5. Влияние внешних факторов тоже сказывается на видимости сетей wi-fi. Так их не будет вблизи источников электромагнитного излучения. Также слабый сигнал будет наблюдаться вблизи потолков, стен, пол и других «препятствий».
6. Причиной невидимости сети может стать сетевой адаптер. Его отсутствие или наличие по-разному влияет на работу гаджета. Если его нет, то и сеть подключаться не будет. А вот при его наличии отсутствие видимости wi-fi объясняется его отключением. На многих моделях ноутбуков есть запрограммированные клавиши (или их комбинация), которые прекращают работу сетевого адаптера.

Те же самые причины лежат в процессе того, что при использовании ubuntu в домашней сети аппаратно выключен wi-fi.

В любом случае способы решения проблем для разных адаптеров (wifislax не видит wi-fi адаптер и kali linux не видит wi-fi адаптер) различны.

Профилактика и безопасность Wi-Fi соединения

При неграмотном использовании Интернета возможен взлом беспроводной сети и передача личных данных посторонним людям. Это в свою очередь может привести к тяжелым последствиям. Для предотвращения такого явления следует соблюдать несколько простых правил:

1. Не стоит подключаться со своего личного оборудования к открытым общественным сетям.
2. А если уже пользователь подключился к ним, то стоит использовать при этом антивирус или файерволл.

Особое внимание надо обратить на правила настройки роутера беспроводной сети:

1. Использовать специальный тип защиты (WPA2).
2. Пароль следует выставлять большой (примерно 50-60 символов). Причем их порядок должен быть разнообразным. В таком случае его сложно будет взломать.
3. Функцию WPS на роутере следует отключить.
4. Функция администрирования через веб-интерфейс должна быть доступна только через кабель.
5. В то время как человек не пользуется Интернетом, роутер должен быть отключен.

Выполнение изложенных правил поможет человеку в долгосрочном использовании беспроводного Интернета.

Что делать, если Убунту не видит вай-фай

Существует множество разных способов, здесь будут представлены самые оптимальные методы.

1 вариант

Инструкция представлена для ноутбука модели Acer с сетевым адаптером марки Broadcom.

1. Войти в «Параметры системы», затем нажать на «Программы и обновления». Во всплывающем окне видно, что системой установлен проприетарный сетевой адаптер. Изменить на пункт «Не используется» и подтвердить свое действие нажатием на кнопку «Применить».
2. Ввести свой пароль. Нажать кнопку «Аутентифицировать». Подождать обновления системы. Перезагрузить устройство.
3. Найти нужную сеть и подключиться.

2 вариант

Здесь подключение будет производиться через компьютерный терминал.

1 вариация

1. Открыть терминал сочетанием клавиш Ctrl, Alt, t.
2. Ввести команды:

sudo apt-get upgrade

sudo apt-get install linux linux-headers-generic kernel-package

sudo apt-get install —reinstall bcmwl* firmware-b43-lpphy-installer b43-fwcutter

После следует перезагрузить оборудование и компьютер хорошо подключиться к беспроводному Интернету.

2 вариация

1. Открыть терминал таким же способом, как и в предыдущем способе.
2. Ввести команды:

sudo apt-get remove bcmwl-kernel-source

sudo apt-get install firmware-b43-installer b43-fwcutter

После также следует перезагрузить оборудование. Соединение с сетью будет восстановлено!

Что делать, если Linux Mint не видит WiFi

Существует только один универсальный для всех способ подключения к беспроводной сети по командной строке.

С помощью команды «iwconfig» следует узнать о всех поддерживаемых конкретным устройством интерфейсах.

1. Проверить включенность интерфейса командой «sudo ip link set wlan0 up» . Узнать о доступных сетях с помощью: «sudo iw dev wlan0 scan | less» .
2. В зависимости от типа защиты и шифрования сети (WEP, WP1/WP2) следует вводить команды:

   «sudo iw dev wlan0 connect [network SSID] key 0:[WEP key]»

   Заключение

   Не стоит паниковать, если Ubuntu не видит WiFi. Следует проанализировать возможные причины и восстановить подключение с помощью приведенных способов. Если не получается исправить положение самостоятельно, то надо обратиться в сервис.

   Wi-Fi Not Working in Linux? Here’s How to Fix it

   

   One of the big challenges that users tend to face with Linux is Wi-Fi. Wi-Fi drivers are often not included in the kernel, and as a result, there are many issues getting non-Intel Wi-Fi modules to work well under Linux. Here we cover what happens when Wi-Fi isn’t working on Linux and how to fix it.

   Also read: How to Move Your Home Folder to Another Partition [Linux/Ubuntu]

   Hardware vs. Software Wi-Fi Issues

   A Wi-Fi connection issue can be either a hardware or software issue. Hardware issues are relatively easy to diagnose – all you have to do is to open the terminal and enter the following command:

   

   This is a simple way to check if your physical hardware is working. localhost works as an address to check the circuitry for your NIC. If this isn’t working, you may need to have some work done on the hardware, whether by yourself or from someone else.

   If that ping comes back clean or you don’t even see your Wi-Fi card, you likely have a software issue.

   Install Drivers from Ubuntu ISO

   If your distro isn’t detecting your Wi-Fi network at all, or if you’re getting errors, then you can try installing or reinstalling the Wi-Fi drivers from the Ubuntu ISO file. First, you need to download the Ubuntu ISO corresponding to your Ubuntu version. (Presumably, you need to download it on a different device or download it using your Ethernet connection on Ubuntu.)

   Place the Ubuntu ISO into the Home directory on Ubuntu. Then in the Terminal, enter the following sequence of commands to mount the Ubuntu ISO to a virtual drive:

   Go to “Software & Updates” from the dashboard, then in the new window, check the “CDrom with [your distro name and version] box” and enter your password when requested.

   Click the “Additional Drivers” tab, then select the “Wireless Network Adapter” option and click “Apply Changes.”

   Issue One: Device Not Detected

   If the wireless device is not detected by Ubuntu (or any distro for that matter), then you will need to access the Terminal and type the following command:

   if you use a plug-in USB wireless card/dongle and

   

   if you have an internal wireless card.

   If the response from these commands comes back with an output similar to the screenshot below, then you are in luck: Ubuntu can find the card. It is usually identified by “Network Controller” or “Ethernet Controller.”

   In the past, many Linux distributions have had difficulty finding the wireless card. Thankfully, support has gotten much better, so this is now a rare instance.

   Additional Commands

   You can also use the following command to test if the machine can see the wireless device; users may need to install lshw on their machine first.

   

   The output should resemble something similar to this:

   If this is the case, and the system finds the wireless card, you can proceed to installing the driver/module as described below.

   Issue Two: Driver Module Missing

   Following on from the successful lsusb and lspci commands, providing your Linux distro can see the wireless card, you can assume that the firmware is working, just that the system has no idea what to do with the card. This is where drivers or modules are needed.

   Go back to the terminal and type the following command:

   You will see a list of modules that are used. In order to activate your module, type the following command where “modulename” is the name of your chipset.

   For example, if your wireless chipset is “RT2870,” it would be as follows:

   

   After this, run the lsmod command again to see if it has loaded correctly.

   Load Module Automatically at Boot

   It is a rare occasion, but sometimes the module will not persist from boot. In this case, you can force it to load permanently. Enter the command below into the Terminal:

   The nano text editor will open. Add your module name at the bottom and save the file. You will need to reboot and check to see if the wireless card can now see networks to enable you to connect as normal.

   If you get stuck, then repeat the process. Thankfully, Ubuntu has some useful help pages in its online documentation that you can also read through. Additionally, you can use the built-in help within the terminal by entering:

   Issue Three: DNS

   It is rare that the DNS will be an issue; however, it is worth investigating should you still have connection issues. From the Terminal, type the following command to assess where the DNS is coming from:

   This will show you the LAN address of the router. If it doesn’t work, you may have to change “wlan1” to whatever your wireless uses. The following command can also be used to grab the designation:

   Once you have this information, your next method is to ping your router’s LAN address. If this works, try to ping Google’s DNS servers:

   With these results, you can establish where the DNS issue is. If all devices within your home or office are giving page load errors, then change the router DNS to Google or Open DNS servers. You’ll have to consult your router manufacturer for how to do this, but it is generally done within the admin pages, most commonly by logging onto 192.168.0.1 or similar.

   If your DNS issue is Ubuntu only, then follow these steps by using the Network Manager GUI:

   • Right click on Network Manager.
   • Edit Connections.
   • Select the Wi-Fi connection in question.
   • Select IPv4 Settings.
   • Change Method to DHCP Addresses Only.
   • Add 8.8.8.8, 8.8.4.4 into the DNS server’s box. Remember the comma separating the IPs and don’t leave spaces.
   • Save, then Close.

   As a final step, either restart your machine or restart the Network Manager from the Terminal:

   Issue Four: No Network Manager

   Let’s say you have removed the Network Manager or uninstalled it by accident. This is a really troublesome situation: you have no Internet and no Network Manager, but there are things you can do.

   Assuming the package is still within your cache, you can go to the Terminal and enter:

   If you have removed this cache, then you can use an Ethernet cable to connect by plugging this into your Ethernet port and running the above command again.

   As a final step, if none of the above works, you will need to edit your configuration file. I selected gedit as the text editor, but you can use your preferred choice and amend the command.

   Amend it to read as follows:

   Then you can restart the interface by entering the below code:

   Further reading of the Linux Wireless subsystem can be found on the kernel.org wiki.

   I tried Ubuntu on two different PC’s one was certified by Ubuntu to work. Neither has WiFi issues when installing, but upon first boot and logging in neither could recognize the WiFi card. I can understand why many first time average users give up on Linux desktop. I mean you would at least want a internet connection to allow for updates even if the driver isn’t the best or latest. Its also ridiculous to expect a newbie to use terminal commands to fix anything. I would rather tell someone to simply try another distro. or possibly find a release that appears to work with similar hardware to yours. Better yet, buy a Chromebook or a MacBook if you can afford it.

   Great to have a checklist for a persistent Linux problem. Shame it’s such a complicated process after all these years. This checklist is something which could be used to create a helper program that anyone could use. Containing the knowledge of the wisest. Usable by not just techies.

   I do agree John. This is my third attempt to use Ubuntu, on different machines and with different builds of Ubuntu on different WiFi networks. Only one has sort-of worked – but that was years ago. Sadly the instructions above have not helped. I’ll continue for another hour or so but am not feeling confident. (The build recognises WifI, lets me type a password, doesn’t give an error message but just ask for the password again, and again and again. I’ve tried several ways to save it).

   I do have to wonder how many others have tried and given up with Ubuntu because of what seems to be a common enough error.

   Very frustrating and very disappointing.

   Really, reading all this just go get on the web makes you wonder if Linux is thé place to be… Which distro would be better suitable to make my connection work without all that mumbo jumbo? Considering I’m a dummie user? My laptop is a simple HP 15 which runs on Win10 home. I want to get rid of that. Thank you!

   Ubuntu is still a good distro for beginner. You can try out a Live USB first to see if the Wi-Fi (and other hardware) work fine on your computer. Most of the time, it will be fine. It is not often to have a Wi-Fi issue in Ubuntu.

   i have installed Ubuntu and can connect to wifi but while i am browsing the wed it shows internet connection failed and never loads the page. it is frustrating but if i my connection is wired it works fast can you please help me please please please please help

   Yeah right… The last two laptops I installed Ubuntu on had no working wifi… It seems a pretty common problem to be honest. My previous laptop had at least a workaround on the internet, each time I updated something linked to the network, it wouldn’t detect the wifi anymore but the script I found would compile and install drivers again, not ideal but I could live with it…
   The new laptop, an ACER Aspire 3, I don’t see any wifi controller after a standard Ubuntu 20 installation. Nothing, zip, and I am now miserable trying to find a script that would allow me to make it work, all the while thinking that I am, in 2021 with Ubuntu, pretty much at a similar point where I was with Debian in the early 2000’s… That’s pretty depressing to be honest!

   Any advice on how to tell if the hardware is broken, or breaking? None of the steps above seem to cover that, and I’m having trouble finding info on that.

   Thanks for your informative post. I have just spent 3+hrs pottering around with linux terminal as you suggest. Unfortunately my computer is still unable to connect (via a Broadcom driver) to the internet. Things seem to fail completely around finding / recognising the driver.

   Is there somewhere where we can download the correct driver for linux and then put it into the correct folder? Which?

   I’m fairly new to linux, but came up in DOS so not afraid of cli. My issue is related to Ubuntu Studio 20.01LTS, and as such most of this article doesn’t work. when i ran the:
   sudo lshw -C network command, it answered with:

   Hi gents
   I wonder I can have a wireless network on Linux Lite (Ubuntu 20.4LTS).My acer machine is dual booted win 10 home (x86) and Linux (x64)
   On Linux I have a wired network to internet but not wireless.On my win there is a normal wifi .Adapters interfaces etc .Cannot understand why on linux not working wifi
   After some googling and some terminal commands like lspci lshw c-network,lsusb or iwconfig I discovered that I don t have any wifi or wireless stuffs.
   Sorry I m not a techie.I downloaded a wireless driver from acers site .But don t know what do after this step.
   Thanks in advance .

   Hi I am new to Linux and in process of Learning.
   i have tried multiple things and still can’t see my Wifi

   It doesnt show up wireless connection. Only able to connect through Wired

   Hey, guys! I’m also a Linux newbie and was struggling with wifi on my Ubuntu 20.04 distro. First I couldn’t see the wireless option anywhere and after today’s upgrade I couldn’t connect to my network with no error message, just asking me again and again for my password (after I decided to forget the pw and connect manually). I did what I did last time to see the wireless list of connections and it worked again although it’d never been perfect coz I experienced drops from time to time while other devices ran perfectly fine. SOLUTION for me was to download b43. Follow instructions from here >>>
   https://ubuntuforums.org/showthread.php?t=2361632&page=2&highlight=b43.zip (wildmanne39 19/05/2017)

   I hope it will work at least for some.

   You see a list of modules that are used. In order to activate your module, type the following command where “modulename” is the name of your chipset.

   sudo modprobe modulename
   For example, if your wireless chipset is “RT2870,” it would be as follows:

   sudo modprobe rt2800usb
   After this, run the lsmod command again to see if it has loaded correctly.

   None of these results say the name of your “chipset”
   the only important piece of info, presumably, which you can from the previous command, is the name of the chipset, so you can proceed to the next step, and this seems to be just left out, or apparently should be common sense from the user?

   so yeah, after typing “sudo lsmod” I see a list of modules, but then there seems to just be a gap in the instructions

   After getting linux up its taken like 3 hours to not learn how to even connect to wifi. this is so lame

   Gid makes a valid point. There is no instruction on what to do next. In Linux Mint I found a module bcma that might be the Broadcom wifi, and I did the modprobe bcma, but nothing happened. So I booted Ubuntu (where the wireless worked and on which Mint is based) and did the same commands, and this time the lsmod listed bcma with some parameters, as in
   bcma 65536 3 b43,brcmsmac
   which were not there on Mint. So the question becomes how do I get lsmod to have those parameters?

   This is my issue too. I see the Broadcom wireless card. I see the name of your chipset under “configuration/driver” after running “lshw -C network” but I don’t see anything like that under “configuration.” When I run “lshw -C network,” I see the Broadcom card, but under “configuration” the only thing listed is “latency=0”.

   Your instructions are very well written for relative newbies like myself, but did you leave out a step?

   Wow, Windows has all the wi-fi issues, not Linux! Out of a dozen or so distros I’ve used, none have had wi-fi or networking in general, problems. Networking may be Linux’s biggest strength. Windows network stack was a roulette wheel for years, never knew if an update would flake out wi-fi or not. Seems OK for the last year or so although ethernet is still clunky.

   After years of Hope-Springs-Eternal with Windows, the speed Linux connects a new install to wi-fi was so good, it seemed suspicious at first. Never had to do anything beyond entering pwds; no CLI stuff at all. Everything from 10 year old cards to brand new ones. All three main Linux branches. Our current router is a Netgear R7800 with third party firmware, since Netgear’s firmware is beyond awful, unstable data collecting junk. Our R7000, third party firmware, worked fine, also.

   The only distros with netorking issues were two headless server installs that were bare bones, add all your own features and I honestly didn’t know how to deal with them at the time. Networking was the least of my issues; nothing worked! Minimal Ububtu 20 is running our home server now; I despise gnome but networking, wired and wireless presented no problems at set up or after. No wi-fi drivers to install. Was fine with Ubuntu 18, too.

   Good advice here for those with problems, although I’m not sure why they would occur. My Linux test laptop is 11 years old, the server has a Xeon processor; wide gap between them. Routers can make a huge difference; rebooting them, connect first with ethernet, etc. Some just won’t work correctly ever.

   So basically, because you never had a problem, means that Linux never has problems on install?? Not my experience, it somehow almost never fully works at install and you need to get help and dive into a gazillion posts and scripts. On my last two laptops, the wifi never worked right after install. I’m trying to solve it right now for the new one…
   So, ethernet networking? Sure, works like a charm… Wifi? It sucks big time…

   I guess my experience is very different from others posting here. I haven’t had a problem with WIFI since WICD was common on installations instead of network manager. The only time I had that had an issue since WICD was a Broadcom wireless card as the driver is not open source which Debian will not allow on the installation media, but you can download it and add it yourself. I put my laptop on a wire and downloaded and installed the Broadcom driver and that was it to get it working. I even used Frisbee on a Puppy derivative without a problem. I was a dedicated distro-hopper for years (though no longer) and never experienced problems.

   After trying everything i found this to work for my MSI GE66 with killer wifi 6

   Enter the following commands into a Terminal one line at a time.

   Step 1 – Download the Latest Git and Build-Essential packages

   $ sudo apt update
   $ sudo apt-get install -y git
   $ sudo apt-get install -y build-essential

   Step 2 – Download the Iwlwifi-Firmware.git repository

   $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
   $ cd linux-firmware
   $ sudo cp iwlwifi-* /lib/firmware/
   $ cd ..

   Step 3 – Create the Backported Iwlwifi Driver for your current setup

   $ git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
   $ cd backport-iwlwifi
   $ sudo make defconfig-iwlwifi-public
   $ sudo make -j4
   $ sudo make install

   This command might be necessary to force your machine to use the Driver from boot:
   $ update-initramfs -u

   Reboot your Computer and verify it’s working!

   BUNCH of THANK you….
   Have Ubuntu 18.04.06 and escaped Windose 4 months ago and tonight, “TRIED” to KDE connect, and using that to tether to my droid, with 4G speeds, and POOFY.. and look at WIFI icon in top bar…. and the WIFI, says “no connection.”
   So I uninstalled all the newly installed thingys, KDE Connect and Rebooted. and “NO WIFI connection…
   SO….. came here and…
   Tried all down to ….
   Right click on Network Manager.
   Edit Connections.
   Select the Wi-Fi connection in question.

   I add “APPLY” and wow…. the WIFI says connected!

   That is a good thing…. lol!… or I maybe used this DELL for Book of Worlds Records, laptop throwing WIN! Windose what the 3 re-installs Win10Pro, and 4 re-installs W7Pro and ALL with admin wifi updates OFF, my Win updated anyway, and never rebooted all 7 TIMES…
   Hasta La vista Windose!

   I’ll still have a bit of Terminal Fever, but slowly getting over with what YOU SHARED HERE! So thanks again, and maybe the neighbors thank you to, not getting hit with a laptop, or scaring their pets!.

   For me and just IMHO, much of the Linux world is a process of re-inventing the wheel. It took years for developers to realize that doing things with a GUI was quicker and easier. But GUI versions of like Ubuntu are works of open source volunteers who don’t have access to all the issues to be seen. Add to that, when a newcomer to the “game” tries to ask questions to gain knowledge, many of the forums reply with arrogance as if you were a bother. It makes the whole process frustrating. ‘Nuff of that.
   I found this post while searching for answers to several issues; I’ll stay on topic and talk of the wifi issues.
   Trying to get the wifi working on an older ThinkPad I got to the point of the possibility of driver issues I followed the instructions to download an iso image but when I get to the instruction:
   sudo mount -o loop ubuntu-*.iso /media/cdrom , it fails returning “failed to setup loop device for ubuntu-*.iso I tried it with the full name of the latest ver as well). So as a noob, not knowing what this instruction is doing, and no explanation of what it’s supposed to be doing, I’m stuck. This is the way of the Linux, Ubuntu, Debian world. I’m dealing similar issue with a Rock64 SBC (a Raspberry Pi variant) that has poor support from it’s makers, and virtually no support from The Linux distro sites, because it’s not a “certified” version for support. For me, all this shows that re-inventing the wheel can be a daunting task. I started out building systems before PC was an acronym., learning machine language, assembly, CP/M, DOS, basic, Fortran on and on. There were always people ready to help. Many of the people I encounter on forums today are arrogant a$$holes that act as if you’re not worth their time. No wonder Microsoft got so big.
