Solution to my Thinkpad E16 Wi-Fi Woes

bugs.launchpad.net Bug #2017277 “Regression: 6.1.0.9-1009 causes RTL8852BE WiFi to ...” : Bugs : linux-oem-6.1 package : Ubuntu

The 6.1 OEM kernel contains backported (from 6.2) support for the RTL8852BE wireless adapter. This has worked fine on my laptop since the support was backported. The latest release, 6.1.0.9-1009 is causing my adapter to occasionally stop working completely. The WiFi disconnects, and GNOME tells me...

I managed to fix the one biggest gripe about my Thinkpad E16: the RTL8852BE Wi-Fi controller randomly dropping out. I actually found this a few days ago, but I had forgotten where I put the file I had edited. You put a file in modprobe.d called 70-rtw89.conf. Both /etc/modprobe.d/ and /usr/lib/modprobe.d work - I used the latter, but for the sake of conventions, you should probably use the former.

You then put in these options for the rtw89 module: options rtw89_pci disable_clkreq=y disable_aspm_l1=y disable_aspm_l1ss=y

Now, my Thinkpad is a fully functional Linux laptop. I will be docking it to an 8 from my initial score of 8.5, but I'm back to liking it for now. If you apply the fix, be sure to update the firmware as well - some older distros have an old version that works but returns a lot of journalctl error on this card.

Update: What do you know! The updated firmware-realtek just went into backports!
