This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Dmesg gives: rtw_8821ce 0000:01:00.0: enabling device (0000 -> 0003) rtw_8821ce 0000:01:00.0: Firmware version 24.8.0, H2C version 12 rtw_8821ce 0000:01:00.0: rfe 2 isn't supported rtw_8821ce 0000:01:00.0: failed to setup chip efuse info rtw_8821ce 0000:01:00.0: failed to setup chip information Such modules are previosly covered by rtl8821ce-dkms. [Fix] Patch set https://lore.kernel.org/linux-wireless/20210202055012.8296-1-pks...@realtek.com/ landed in v5.12-rc1, as well as WLAN firmware updates in commit c5e3240eff0f ("rtw88: RTL8821C: Update firmware to v24.8"), which is already available in Hirsute version 1.195. Bluetooth firmware should have been the latest 0x829a_7644 in both Focal/Hirsute. [Test Case] With patched kernel, wlan interface should be up and running: rtw_8821ce 0000:01:00.0: enabling device (0000 -> 0003) rtw_8821ce 0000:01:00.0: Firmware version 24.8.0, H2C version 12 rtw_8821ce 0000:01:00.0 wlp1s0: renamed from wlan0 [Where problems could occur] Previously this hardware piece can only be driven by external DKMS modules, so with this driver patched, users can now use in-tree driver, but may experience the difference between them in power consumption or feature supportness. [Other Info] While Bionic/Focal LTS is still using rtl8821ce-dkms for RFE Type 2 cards, there is no plan to introduce such change to them. So they'll be upgraded only at the next point release with kernel >= 5.11. ========== original bug description ========== 8821ce is being upstreamed in https://lore.kernel.org/linux- wireless/20200603094218.19942-1-yhchu...@realtek.com/ .
