Intel 7265 bluetooth linux

Intel Dual-Band Wireless-AC 7265

Внезапно(!) обнаружил, что у меня в ноуте стоит обычная Intel Wireless-N 7265. Решил менять на Dual-Band Wireless-AC 7265.

В продаже нашлись карточки 7265.NGWG.W939155 и 7265.NGWGC.SW939199. И если поиск по первой вывел меня сюда https://qdms.intel.com/Portal/SearchPCNDataBase.aspx?mm=939155 то по второй вообще ничего найти не могу, да и гуглится она только по нашенским магазинам.

Вопрос: как понять чем они отличаются и какую брать?

Отличаться могут две вещи
1) Наличие/отсутствие Bluetooth
2) Форм-фактор
Тут смотрел? http://forum.ixbt.com/topic.cgi?id=14:59499

Судя по http://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/du. мне как раз нужен 7265NGW. А у сабжевых модулей отличие только в коде (NGW — форм-фактор M.2 2230) — G.W939155 и GC.SW939199.

Небольшой оффтопик. Ты же в курсе, что этот модуль жутко глючный? Постоянные разрывы, не дальнобойный. Я вот недавно взял 8260 — он вроде получше, но даже в нем толком не работает Bluetooth.

У меня сейчас Intel Wireless-N 7265, проблем с wi-fi нет, по синезубу подключена клавиатура и работает прекрасно, но мне нужен диапазон 5ghz. Да и глючный же вроде 7260.

Introduction

iwlwifi is the wireless driver for Intel’s current wireless chips. For older chips, there are other drivers:

Features

Supported Devices

The following devices are supported (since kernel version):

For more information on Intel Wireless products, please visit Intel Wireless.

Git repositories

There are four repositories that we maintain:

Firmware

If not installed by your distribution already (check the packages) you can get the latest firmware from linux-firmware.git.

If you do get it from linux-firmware.git, you’ll have to copy the files to the appropriate location on your system. Where that appropriate location is depends (again) on your system distribution. You can typically find this location by looking in the udev scripts of your distro, the default on most distributions is /lib/firmware.

Installation of the firmware is simply:

You can now load the driver.

Support

If you have technical issues or general questions about Intel Wi-Fi on Linux, please contact Intel Customer Support.

For bug reports and debugging, please see the page dedicated to that.

7260, 3160, 7265, 7265D, 3165 and 3168 support

Those devices will not be supported by the newest firmware versions: the last firmware that was released for 3160, 7260 and 7265 is -17.ucode. Bug fixes will be ported to -17.ucode. 7265D, 3165 and 3168’s latest firmware version is -29.ucode. In order to determine if your 7265 device is a ‘D’ version, you can check the dmesg output:

The revision number of a 7265D device is 0x210, if you see any other number, you have a 7265 device.

Firmware_class dependency

The firmware necessary to support the devices is distributed separately under the firmware license.

Note that many distributions ship the firmware, you could install the “linux-firmware” package or similar. If that doesn’t work, or you need newer firmware, read on.?

The driver loads the firmware using the kernel’s firmware_class infrastructure. More information can be found under in the Documentation/firmware_class/README file in the kernel source. In order to function correctly the driver requires this to be enabled in your kernel. When you configure the kernel, you can find this option in the following location:

You can determine if your kernel currently has firmware loader support by looking for the

definition on your kernel’s

In addition to having the firmware_class support in your kernel, you must also have a working userspace infrastructure configured. The steps for installing and configuring this are very distribution specific and the tools differ, but distributions have this enabled.

Once you have the firmware loader in place (or if you aren’t sure and you just want to try things to see if it works), you need to install the firmware file into the appropriate location.

About the backport tree

We merge the updates coming from the backport infrastructure on a regular basis. This means that the bleeding edge of the backport tree will run against decently recent kernel (usually against Linus’s tree). If you checkout an earlier branch / commit in backport-iwlwifi.git, you might not be able to work against the most recent kernel. Please keep that in mind. We have a release cycle based on the backport tree. These Core releases can be very useful for someone who wants to integrate our Wi-Fi solution into his home made system.

About dual-boot with Windows and «fast-boot» enabled

If you have a dual-boot machine with a recent version of Windows and start seeing problems during initialization of the WiFi device when booting Linux, the problem could be due to the “fast startup” feature on Windows.

With this feature enabled, Windows don’t really shut down the entire system, but leaves things partially running so you can start the machine faster again. Try to disable this option, on Windows 10 it should be in “Control Panel→Hardware and Sound→Power Options→System Settings”. Select “Chooose what the power buttons do” to access the System Settings from the Power Options. Then disable the “Fast Startup” option in “Shutdown Settings”. This will cause Windows to fully shutdown and may solve the issue.

About platform noise

Wi-Fi heavily relies on radio frequencies, and those are subject to interference. Interference may come from another Wi-Fi device, or from many other non Wi-Fi devices (e.g. microwaves) that operates on the same frequency, and it might also come from other components of your own device/computer – this is known as ‘platform noise’. Platform noise depends on the actual platform/computer and its design/manufacturing, and not on the Intel Wi-Fi module.

Some common sources of platform noise might be:

This kind of interference might happen on 2.4GHz band, it is much less likely to happen on 5.2GHz band. Also note that using 40MHz (and not 20MHz) channel bandwidth will increase the probability to suffer from platform noise (since more frequencies might impact the Wi-Fi performance).

Some potential work-around options to this issue:

The fact that one of these options helped doesn’t prove that the issue being troubleshooted is ‘platform noise’, but it may be an indication.

Another thing that can be tried is to modify the antenna position. The antennas are typically located in the lid of the laptop. It is worth trying to open / close the lid or to rotate the system and see if it has any effect.

About the monitor / sniffer mode

Our devices support monitor mode. When you have VHT APs around, you should load the iwlwifi module with

This will put lots of pressure on the memory subsystem, but it will allow you to hear 12K long packets. You may see firmware crashes in case you didn’t set that module parameter.

About iwldvm support and known issues

Wi-Fi / Bluetooth coexistence

Having Wi-Fi and Bluetooth running at the same time is a challenge. These scenarios have been tested thoroughly on 7260 and up, less so on earlier devices. This is why some people may face issues with devices that are handled by iwldvm. For users of these devices who have problems when Wi-Fi and Bluetooth are running concurrently, we suggest to disable BT Coex by loading iwlwifi with bt_coex_active=0 as a module parameter.

Power management

Starting from 3.17, power management has been disabled in iwldvm because users reported it improved the behavior and was a valid work around for issues. The commit that disabled power management is here.

[Intel Dual Band AC 7265] Bluetooth not working BUT wifi does. Whats wrong?

Problem finally solved, take a look to the last thread if you have the same issue

Hello dear forum members. This is my first post in here.
I recently purchased a new laptop since my old one is over 8 years old. Got quite anything working except the built-in bluetooth. After wasting days of my life (online research so far) I desided to ask the community to help me.
Just to clarify some things out. I’m linux user since my whole life, but I can’t fix this problem for some reason.

The Laptop [TUXEDO Book XC1705] comes with the Intel® Dual Band AC 7265 + Bluetooth pci card. Wifi works 100% without any drops or anything else But Bluetooth doesn’t.

This is also quite strage for me. Why is shows 8260 and not 7265? Does the manufactor lie to me

There is no BD address. Is that because it cannot activate the device?

Let me know if you guys need some more info.
I hope someone can help me get that damn built-in bluetooth to work. I won’t waste a usb port for external bluetooth dongle anymore, especially when I have a built-in one.

EDIT: some side note
bluetooth services works normal, with my external bluetooth usb dongle I can use everything like speakers, keyboards, mice and stuff

Re: [Intel Dual Band AC 7265] Bluetooth not working BUT wifi does. Whats wrong?

I am not familiar with that bluetooth chipset

It almost looks like the dmesg info was from after a suspend/sleep mode. does the dmesg info look the same after a shutdown and boot?

Re: [Intel Dual Band AC 7265] Bluetooth not working BUT wifi does. Whats wrong?

I never put laptops in sleep/standby mode, ONLY hibernation. But the dmesg output never changes across reboots or resumes from hibernations.
I even tried symlinking different firmware files, but it displays all kind of errors in dmesg and bluetooth just won’t work.

Also, the device is NOT softlocked nor hardlocked. This error is indeed very strange. Perhaps I should contact the manufactor, maybe they can help a little bit more.

Re: [Intel Dual Band AC 7265] Bluetooth not working BUT wifi does. Whats wrong?

bump.
just can’t get that damn bluetooth to work. no one that can help?

Re: [Intel Dual Band AC 7265] Bluetooth not working BUT wifi does. Whats wrong?

Might be worth using a 15.10 live CD/USB media if you can, and testing out the updated bluetooth support.

Re: [Intel Dual Band AC 7265] Bluetooth not working BUT wifi does. Whats wrong?

So, I booted up into a 15.10 live session to check some things. Bluetooth and Wifi is working out of the box. (:
Now the strange part: I just played around a little bit — never installed or touched the system in any form -, than I rebooted back to the main OS and out of the sudden bluetooth works. What is even happening whyyyy-what?

Can it be that the live session did something with the hardware? That CAN’T BE.

I’m not sure if I should mark the thread as [SOLVED]

EDIT: if things don’t break «out of the sudden» the next 2

3 reboots, than i will mark the thread as solved

Re: [Intel Dual Band AC 7265] Bluetooth not working BUT wifi does. Whats wrong?

Well, that’s good news

If your existing install doesn’t survive a cold reboot with a working bluetooth connection, at least it looks like an install of 15.10 will sort you out.

Re: [Intel Dual Band AC 7265] Bluetooth not working BUT wifi does. Whats wrong?

Good news and finally solved this pesky issue (without updating ubuntu itself)
NOTE: after a reboot I had the same issue with firmware not sending

Here are the steps what I did to help others.

1. Download the current kernel source from http://kernel.ubuntu.com/

kernel-ppa/mainline/ (for me 4.1.0-rc8)
2. Apply the patches according to the SOURCES file
3. Apply this patch here -> https://lkml.org/lkml/2015/7/31/1248 | 4.1-stable review patch, [PATCH 4.1 017/267] Bluetooth: btusb: Fix secure send command length alignment on Intel 8260
4. Compile the kernel. (took a very very long time. )
5. Extract the bluetooth folder from (deb)/kernel/driver/bluetooth and place it into my real modules folder (override files, make sure that you create a backup first)
6. Run modprobe -r btusb and modprobe btusb
7. Bamm!! Bluetooth works! (without updating kernel/ubuntu system)

I finally can use my internal bluetooth which also survives cold reboots (: and the best of all: wifi didn’t broke, now both works like a charm

but thank you anyway for the 15.10 livecd tip. maybe someday I will upgrade — when the time has come

No wireless/wire connection – Intel 7265

Post by jcw » Thu Jun 09, 2016 6:53 am

I am new on Mint as I just installed it today, instead of Ubuntu 16.04. I installed Mint 17.3 Cinnamon 64bits on an Asus UX305FA, and doesn’t have any internet connection, whether via wireless or wire… It doesn’t show me any available network.
Before installing it, I tried it using a Live USB and didn’t have any problem connecting to wireless.

I checked few similar topics on the forum but unfortunately couldn’t find the solution.
Here are some results from the terminal :

How did you install the 4.4 kernel?

It is possible to use that wifi in 3.19 if needed
