WiFi card RTL8723bs not recognized

vijuarez · 2018-03-22 13:40:36

Hello!

I have been trying (for now a long time) to set up a functional Arch Linux install on my Acer Switch One 10, with varied levels of success. This particular post is for getting the WiFi working. The card is not recognized, and I have been unable to get it to work, relying on an Android to tether via USB. The Arch Wiki mentions installing the corresponding drivers from the AUR, but both of the drivers fail to even build at all. I tried using the Testing Kernel, but no luck either. I'm currently running the 4.14.28-1-lts kernel. I have also tried installing a number of drivers from github, but they usually fail to build or do nothing at all (my current install is fresh, I have only tried to install the AUR drivers).

I'll be grateful for any help.

Welcome to the forums vijuarez

I'm afraid 'failed to build' isn't an error message and contains no useful information at all for us to help you.
Please read https://bbs.archlinux.org/viewtopic.php?id=57855 and try again.

Hello Slithery, thanks for answering and sorry for my late reply! (busy week)

When I posted I had lost all hope of getting the drivers to work, so I forgot to specify how the builds failed. I was expecting a different solution, sorry about that!!

1) AUR Driver

Here's the error log

2) AUR Driver DKMS edition
This one actually builds and installs, but fails when building from DKMS:

[vijuarez@luna ~]$ sudo dkms autoinstall

Kernel preparation unnecessary for this kernel. Skipping...

Building module: cleaning build area.... CONFIG_RTL8723BS=m make -C /usr/lib/modules/4.14.28-1-lts/build M=/var/lib/dkms/8723bs/9ea0240/build modules............................................(bad exit status: 2) Error! Bad return status for module build on kernel: 4.14.28-1-lts (x86_64) Consult /var/lib/dkms/8723bs/9ea0240/build/make.log for more information.

Here's the actual log

3) Hadess's driver (github)

When using make and sudo make install, they produce no output. I can now use modprobe to load the r8723 module, but there seems to be no change. iw dev reports nothing and it doesn't show up in KDE Information Center.

4) AnthonyWong's driver

This is marked as obsolete as the driver was merged into linux, I tried to install it anyways. It failed. As I mentioned in the first post, I have used the regular linux kernel, the testing one and currently LTS without change.

Here's the log

Thanks!

As the kernel contains the r8723bs module what does dmesg show? What is the VID:PID of the device from lspci / lsusb?

vijuarez · 2018-03-24 21:43:04

Hello loqs and thanks for answering!

The device doesn't seem to be recognized at all... I'm certain it's there, because I used it on Windows, but...

Does rfkill list any devices?

Nope, no output at all.

loqs · 2018-03-25 16:17:43

What is the output of lsmod. Does adding the boot option pci=nocrs have any effect?

vijuarez · 2018-03-25 17:11:03

lsmod output

Adding the pci=nocrs boot option seems to have no effect, at least no changes in lsusb/lspci output.

lsmod output with pci=nocrs boot option
