WiFi adapter not recognized

[oci]

Hello. I am very new here! I am using EOS and I like it!
I have no other experience with Linux. I like the lightness

Now on the problem: my WiFi adapter is not recognized. It is combined with Bluetooth, which is available in setting menu and “sees” some devices around! I am using Lenovo G505 2013 laptop. EOS ver: 3.8.7 (201005-133640)

I did the commands in Terminal and I can see it:

lspci; lsusb
…
01:00.0 Ethernet controller: Qualcomm Atheros QCA8172 Fast Ethernet (rev 10)
02:00.0 Network controller: Broadcom Limited BCM43142 802.11b/g/n (rev 01)
…

PLS see the attached report: eos-diagnostic-201108_100705_UTC 0200.txt (679.5 KB)

I have no hardware buttons fir wifi, try to update BIOS, but some is wrong.

PLS Help!

Hello @oci, unfortunately, the BCM43142 driver had a license issue and it is not part of the recent kernel version.

No wifi adapter found acer

Hi, the main issue is, that previously the WiFi Adapter was supported by Linux with Kernels <5 with a proprietary driver (Broadcom-STA) which is no longer included in recent kernels

And my suggestion would be getting a USB dongle,

Hello @Peter_Eles, After some searching, unfortunately, this wireless chipset “Broadcom BCM43142” is not supported properly in most of the kernel versions. I would suggest you get a USB WiFi dongle for this laptop, you may reference this list: https://elinux.org/RPi_USB_Wi-Fi_Adapters#Working_USB_Wi-Fi_Adapters In the meantime, I am reporting this issue to the Endless Engineering team, hopefully, this will be fixed in future releases.

HTH,

Thanks very much for your answers.

Which Linux distribution can I try or this issue will always came up?

The issue is with every current Linux distribution as everyone is now using Kernel 5.x except for some older distributions. I second the suggestion from Yung to get either a Dongle - or, if you are proficient in using a screwdriver and doing basic work with computer electronics, grab a Mini PCI Express Wireless card (i suggest you to use a Intel 7260) and simply replace yours.

It’s easy according to the service manual: https://download.lenovo.com/consumer/mobiles_pub/lenovo_g400sg405sg400stouchg500sg505sg500stouch_hmm.pdf
