Title:
rtw89_pci constantly drops connection with old firmware
Status in linux-firmware package in Ubuntu:
Invalid
Status in linux-firmware source package in Impish:
Fix Committed
Bug description:
[Impact]
This was on a new Lenovo P14s Gen2 AMD. I'm using Ubuntu 21.10
(impish)
The current linux-firmware package (1.201.4+1.201.3) ships with
realtek rtw89_pci firmware (/lib/firmware/rtw89/rtw8852a_fw.bin)
version v0.13.8.0.
My wifi chip wasn't able to keep a connection for more than a minute when
connected to a Rodgers "Advanced Wi-Fi Modem". I searched around tried
disabling the power_save and stuff. But that had little to no effect. I was
about to open an issue on the upstream project and did a last ditch attempt to
see if there were any firmware updates... I found linux-firmware.git and it had
two newer versions!
- v0.13.30.0 (was submitted in May 2021, but it took until october 2021 to
show up)
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/rtw89/rtw8852a_fw.bin?id=ec17b637b7ab928ca7ebc0389e0e3921f1cc7d17
- v0.13.33.0 (was submitted in November 2021 and got merged in December
2021):
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/rtw89/rtw8852a_fw.bin?id=4a7e1f5cabaebe5c044b94b91149f35471d1e983
I've downloaded and installed the latest "v0.13.33.0" on a whim and
rebooted. And what a pleasant surprise: Instantly, my wifi connection
lasted until the rest of the day.
Could you please consider updating this realtek firmware in the next
release? Thanks!
[Test Case]
See above.
[Fix]
Cherry pick two commit to match current Jammy:

ec17b637b7ab ("rtw89: 8852a: update fw to v0.13.30.0")
[Where Problems Could Occur]
Limited to wifi using RTL8852A HW.
