Brunch r105-unstable WiFi issues - broadcom chip #1679

Open tejasraman opened 1 year ago

tejasraman commented 1 year ago

See #1677 I recently installed Brunch on a Sandy Bridge MacBook Pro with CrOS 105 + Brunch 105 unstable. My WiFi card shows as "on", but no networks show up. I tried the blacklist in the wiki but it doesn't work.

Same here on a MacBook Air 11' mid 2013. Worked fine with r103 - not working after updating to r107 stable or unstable. Same diagnose as above: "My WiFi card shows as "on", but no networks show up."

Downgrading from r107 to r103 was possible without problems.

So the bcmwl driver is broken. What kernel are you using?

weberk commented 1 year ago

I think the name of the driver module is broadcom_wl. Here my kernel options: options=broadcom_wl,enable_updates,acpi_power_button

Since I am on r103 the driver is working now. The kernel is: chronos@localhost /var/log $ uname -a Linux localhost 5.15.45-brunch-sebanc #1 SMP PREEMPT Thu Jul 21 18:12:24 UTC 2022 x86_64 Intel(R) Core(TM) i7-4650U CPU @ 1.70GHz GenuineIntel GNU/Linux

I knew that and it works in a Linux env... Could you try a different kernel (eg 5.10-MacBook)?

weberk commented 1 year ago

Dont know how to switch a kernel. Just to be clear: WIFI is working with my current kernel which was included in brunch r103. Currently I am using ChromeOs r107 with Brunch r103. Everything operational now.

Whats not working is Brunch r107. Seems there was a regression between those two releases.

I have AzureWave AW-CE123H (BCM94352HMB) and have the same problem. As far as I remember, it's broken since Brunch r103 unstable 20220722 build. @sebanc

tejasraman commented 1 year ago

Interesting..... I'll look into this.

sebanc commented 1 year ago

This build should re-add broadcom_wl support: https://github.com/sebanc/brunch-unstable/releases/tag/r107-unstable-20221115

However, note that the original chromeos version of wpa_supplicant is not compatible with broadcom_wl module and that this method will break at some point.

Thanks for the fix sebanc and tejasraman! Wifi is working again in r107 unstable:
