The changes made to linux-firmware 1.201.1 on impish has destablized use of a Gigabyte GC-WB867D-I REV Bluetooth 4.0/Wireless AC/B/G/N Band Dual Frequency 2.4Ghz/5.8Ghz Expansion Card. Under the new linux-firmware 1.201.1, no wifi is available under Gnome in about 80-90% of the boots. Under the prior linux-firmware 1.201 release, the wifi always appears under Gnome. Below are the differences in syslog for the broken linux- firmware 1.201.1 release...

[Where problems could occur] While there is explicit FW API for kernel version compatibility checking, this might introduce some hidden glitches that we don't know yet. [Other Info] MT7921 is supported since Impish 5.13 kernel, and Impish already has the latest Bluetooth firmware, so only the WiFi one is proposed. For oem-5.13 and oem-5.14 in Focal, both firmware updates for Bluetooth and WiFi are required. ========== original bug report ========== [Reproduce Steps] 1.Add the wireless card MT7921 to SUT,Install the Ubuntu OS. 2.During OOBE, Open the settings, there is no wireless settings in the panel,and the wifi cannot be used,issue occurred. [Results] Expected Result:The wireless settings should be exists and wifi can be used Actual Result:The wireless settings not exists and wifi can not be used To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1947829/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
