Realtek rtl8723bs sdio adapter

Ok, I’m expecting a reply along the lines of «um have fun, and good luck, you’ll need it»

I’ve installed ubuntu 14.04.1 on my Pipo W2. It’s a windows 8.1 bay trail tablet, the wifi chip in it is a realtek 8723bs wifi/bt chip. This is not supported of course by ubuntu. so no wifi right now. Ubuntu boots with no problem, and I’ve got grub2 configured now for the stupid 32 bit uefi setup. I’ve found the following info to build a driver for the wifi: https://github.com/hadess/rtl8723as

This is from someone who’s doing similar work on a different bay trail tablet with the same wifi chip.

Other problems with this tablet that might be relevant to answers: It boots 14.04 ubuntu just fine. but wont boot 14.10 at all. the screen goes weird even with video=VGA-1:800x1280e reboot=pci,force in the command line, and no quiet or splash. Hard to troubleshoot what’s going on with 14.10 when I cant even read any text to post, so I’m stuck working with the older kernel in 14.04

The problem is, while I’ve been using lubuntu for a couple years, I don’t know anything about how to turn this into a working wifi driver to get it working. More to the point, I don’t know enough to really be sure of what questions to ask, which really makes it harder to just google the information and research it. I am not looking for someone to spoon feed me step by step instructions, just for someone to point me in the right direction, so I can try to work this out. Even if it takes a couple months of reading and experimenting to get it to work, I want to get this working and learn as much as I can in the process. Anyone help me with what I should be looking up?

Re: Realtek rtl8723bs sdio adapter

Ohhh, sorry! I can’t give you the answer you expect.

The process is usually something like this, with a temporary working internet connection:

It ‘makes’ with one warning but no errors on my 14.10 system. It doesn’t call for firmware, so, assuming your device is covered, it ought to spring to life.

I await your report of success.

Re: Realtek rtl8723bs sdio adapter

ok, thank you thank you. everything went fine, until the end, when i just get the following:

Re: Realtek rtl8723bs sdio adapter

It worked for me.

Does it drive your device?

Re: Realtek rtl8723bs sdio adapter

well, it worked, at least in the fact that it didn’t have the error that showed up last time. however, no luck with wifi working =/

Re: Realtek rtl8723bs sdio adapter

I’ll amend my instructions above for the benefit of the searchers.

Let’s see some diagnostics:

What is your reference that suggests this is the correct driver so I may study the prior art?

Re: Realtek rtl8723bs sdio adapter

references that it’s the right chip is, with my windows installation the wifi/bluetooth shows up as realtek rtl8723bs sdio (sorry no screenshot handy atm)

googling info on the realtek rtl8723bs I found multiple references to the Onda v975w windows tablet, and threads asking for help regarding it’s wifi.

and the website the person who is working on porting linux to the onda v975w is here
https://wiki.gnome.org/BastienNocera/Ondav975w

(the link I posted earlier to the driver is from his website)

Re: Realtek rtl8723bs sdio adapter

How about the diagnostics I requested?

If you are having trouble finding the pipe symbol | just post the wireless part of:

. that relate to RTL or 8723. Thanks.

Installing Realtek rtl8723be driver for Ubuntu, Debian or Fedora

Originally written by Chirath R

I have been searching for a fix for the wifi problems in my HP Pavillion ab-028tx. It’s having a Realtek rtl8723be Wifi Card. For a long time, there was no perfect driver for this device. I tried many drivers and none of them fixed the disconnection and low wifi range problems. At last, I found a fix from ubuntu forums. Follow these steps to get your wifi working in Ubuntu.

• Get into your BIOS(in my case I had to press f10 after turning on my laptop). Then go into System Configuration->Boot options and Disable secure boot. This is very important as third party drivers won’t work in secure boot mode as they are not verified.
  • Save and restart(f10), open up a terminal (ctrl + alt + t) and type the following commands in order.
  • Installing new driver for the Realtek wifi chip.

  Note: its suggested to have latest kernel installed(Linux kernel 4+).

  Step 1:

  Ubuntu :

  Debian:

  Step 2:

  Common steps for all three OSes.

  • If you are not able to see your wifi networks, follow the steps below :
  • Download the driver by clicking “Download ZIP” from GitHub.(Note that the GitHub driver must be the master branch) or clone the driver by using the link https://github.com/lwfinger/rtlwifi_new.git
  • extract it to your home directory and open a terminal.
  • Execute the following commands :

  Step 3:

  Ubuntu and Debian

  Fedora

  Step 4:

  Common Steps

  • If you are unable to get wifi even now, change the antenna input to #2 using the command:
  • note : try changing ant-set=1 or 0 if it doesn’t work for u.
  • Now your Wifi will be working perfectly as in windows, now set input #2 as permanent.

  And reload the module.

  Now your WiFi should be working perfectly 🙂 .

Thank you very much, this helped my bluetooth connection rtl8723be

Thanks a lot.. it really help. ur the best.

Sorry, when I type:

$ sudo apt-get install linux-headers-$(uname -r) gcc g++ build-essential dkms git

I receive the following message:

E: Unable to locate package rtl8723be

Please, can someone explain me what’s wrong?
Many thanks in advance!

Are you connected when you try this ?

please make sure you are in right directory

Works Perfect on latest Fedora 27 Kernel . just pull it from git with “git clone https://github.com/lwfinger/rtlwifi_new” instead of downloading, to avoid “This branch is abandoned” message

help

Thank you very much for the post!, there is only one small problem on Step 1; the http://ppa.launchpad.net/hanipouspilot/rtlwifi/ubuntu artful Release repository, can not be updated safely and is deactivated, it does not have posting file Release “sudo add-apt-repository ppa:hanipouspilot/rtlwifi”.
Thank you so much!

Ok, following Step 2, Step 3 and Step 4 with the master branch, and antenna 2. Thanks a lot!

Hola, yo andaba con ese problema en Debian, no me funciono la solucion de este post, pero esta si: https://github.com/roopansh/rtl8723be_wifi

Hello, how do i get know which driver is installed? I am new at Linux specially a kernel modifications, but i do this:
[eugenious@cumputer

]$ modinfo rtl8723ae
filename: /lib/modules/4.14.11-300.fc27.x86_64/kernel/drivers/net/wireless/realtek/rtlwifi/rtl8723ae/rtl8723ae.ko.xz

parm: disable_watchdog:Set to 1 to disable the watchdog (default 0)
(bool)
parm: ant_sel:Set to 1 or 2 to force antenna number (default 0)
(int)

It feels like still loaded default driver. At least on speedtest.net i am still getting like 20-30% of my real speed.
(My Android phone getting 100% as i have in contract with my net provider)
Also, my fedora ofc like 2-3 times a week getting new kernel update, and obliviously i have to reinstall this driver everytime. But i am ok.

I’m unable to view any wifi networks when I restart my laptop. But I can view them when I enter these commands
sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=2
Should I execute these whenever I login? Is there any permanent solution?

I missed the step 4. I got it now. Thanks!!
