24.04 + kernel 6.17 + latest linux-firmware => problematic bluetooth and wifi
https://askubuntu.com/questions/1564536/24-04-kernel-6-17-latest-linux-firmware-problematic-bluetooth-and-wifi
I have a Lenovo ThinkPad T14s Gen 6 (AMD) running Ubuntu 24.04.4. After upgrading to kernel 6.17 and the latest linux-firmware yesterday, I still have Wifi connection but there are some other Wireless issues.
My laptop can only discover 2.4G networks. At home I have a dual-band router, but only the 2.4G one is listed.
My MX Master 3S becomes super laggy via bluetooth connection. (It works fine with the bolt connector.)
I am staying on 6.14 for now, where all the problems above don't exist. Any ideas on how to solve these issues? Thanks in advance.
