[Solved] WiFi not found

[linuxandhamsandwich]

Hello all,

I'm new to Linux and this forum so hoping to learn in this process as well as have my problem solved. I recently purchased an ACEPC T8 (also called W8 Pro) that came pre-loaded with windows 10. I wiped windows 10 and installed Linux Mint 19.1 'Cinnamon'. After the installation my computer does not recognize the built in wifi adapter. It does not appear in lspci or lsusb. I currently have an ethernet cable plugged in to connect to the internet. I cannot locate the card in the bios either.

Could this be a driver issue? I have installed all updates that mint suggested and still no luck.

Thank you to anyone that could help with this.

Hello, linuxandhamsandwich.

Welcome to the Linux Mint forum.

Let us start addressing your wifi problem in the common way, by permitting us to read what inxi "thinks" about your machine.
Please, open a terminal window.
Execute the commandline

Code: Select all

inxi -Fxz

precisely as it has been typed here.
Please, mark the complete text output, which inxi will display in the terminal window, copy it into the clipboard (<ctrl><shift>c) and paste it into your next reply.
This will give us a concise overview on your hardware and on the drivers, which Mint uses. It will also tell us whether Mint detects your wifi adapter at all.

Best regards,
Karl

Great, one of those netbooks that have SDIO wifi cards, see the wireless script link in my signature and post results

[linuxandhamsandwich]

Jeremy,

Thanks for your reply!

I ran what I believe were your script commands and produced this link:
https://termbin.com/icc6

Thanks!

[JeremyB]

Do

Code: Select all

sudo apt remove bcmwl-kernel-source

And run the wireless script again

[linuxandhamsandwich]

Done.

Any results from terminal for

Code: Select all

dmesg | grep 8723

[linuxandhamsandwich]

Jeremy,
here is the result I get:

[ 41.872347] input: gpio-keys as /devices/platform/gpio-keys.1.auto/input/input11

[JeremyB]

Lets try

Code: Select all

dmesg | grep -i sdio

From what I found during a search is that it should have a rtl8723bs wifi. The kernel you have does have a module that should support it

[linuxandhamsandwich]

Thank you so much for your continued help.

Here are results the previous command:

[linuxandhamsandwich]

I still can't see the wifi adapter, is there a way to install the module I'm missing?

[JeremyB]

Can you look in BIOS settings to see if wifi/WLAN is enabled?

[linuxandhamsandwich]

I can't see wifi/WLAN anywhere in the BIOS, I just checked every page.

[linuxandhamsandwich]

Hey Jeremy,

I decided to switch to linux mint Xfce and I'm still having wifi issues.

I ran dmesg | grep -i sdio

here are the results:

Reboot

[linuxandhamsandwich]

It worked!

I'm connected and running through wifi now.

Thank you so much!

I just ordered a ACEPC T11, be here tomorrow, 3/4/19. I've been looking on the ACEPC forms and there's several post on the wifi card not detected. Someone posted the only distro to detect the card was Debian. That being said I would think Ubuntu/LM should detect it as there are based on Debian. Also I was wondering if BT was working now also.
Just a thought.
