Issues with TP-Link T3U Plus since update

[Robon]

Since the last larger update, including kernel bump to 6.12, my issues with the WiFi adapted have increased.
(Note that despite that, I’ve been trying several old kernel versions and the problem remains the same)

Up until now the device worked well, except for turning off under heavy load every now and then, but reconnecting the device would fix it.
Since said update, the device won’t work or is very slow.

Most common message in dmesg is:
rtw_8822bu 2-4:1.0: failed to get tx report from firmware

Sometimes also:
rtw_8822bu 2-4:1.0: firmware failed to leave lps state

Every now and then when disconnecting, this:
[ 1728.532401] rtw_8822bu 1-4:1.0: write register 0xc4 failed with -71
[ 1728.532506] rtw_8822bu 1-4:1.0: rtw_usb_reg_sec: reg 0x4e0, usb write 1 fail, status: -71

For additional information, when the device was still satisfyingly functional, I had the kernel parameter usbcore.autosuspend=-1 set.
I’ve been experimenting with usbcore.autosuspend=0 and pcie_aspm=off to sucess of varying degrees, the firmware issue seems to pop up randomly but in most cases when booting up the machine.

[HowTo] Request support

Difficulty: ★☆☆☆☆ Strong of its many members, the Manjaro support forum can provide you help whenever you have an issue with your Manjaro installation. But in order to work efficiently, we shall also ask you to follow three major points. Provide context Simply signaling an issue is rarely enough to understand how it occurred. It is thus important to provide details on how it happened: Detail prior actions leading to the issue. List solutions and guides you already tried, with links whene…

• If you give us information about your system, we can see what we’re talking about and make better suggestions.
• You can do this by using inxi in a terminal or in console.

sudo inxi --verbosity=8 --filter --width 

• Personally identifiable information such as serial numbers and MAC addresses are filtered out by this command

3. Copy the output from inxi (including the command) and paste it into your post.

[HowTo] Post command output and file content as preformatted text

Difficulty: ★☆☆☆☆ Formatting differences Discourse – this forum’s engine – uses Markdown to format its posts, and removes “unnecessary” whitespace. Terminal commands often produce output formatted so that they are better readable by the user, taking advantage of the monospaced font used. Programming code often rely on indentation to make it more readable. Using preformatting in Markdown Markdown includes a pattern to provide preformatting when necessary. You only need to put the part to form…

For additional information

Please provide (at a minimum) the inxi system information requested to allow some context.

inxi --admin --verbosity=8 --filter --no-host --width

For additional information, when the device was still satisfyingly functional, I had the kernel parameter usbcore.autosuspend=-1 set.

What is it/was it supposed to be doing?
As well as this?

@Robon

usbcore.autosuspend=0

It somehow suggests to me that the issue might be power savings related - usb power saving … turn it off so that the card does not try to enter this mode.
