Ubuntu Version :
Desktop Environment (if applicable):
Problem Description :
The problem was fixed in version 6.14.3, I updated with mainline and Wifi worked successfully.
The problem can be checked here:https://bugzilla.kernel.org/show_bug.cgi?id=219967
committed 12:32PM - 20 Apr 25 UTC
The reset handshake attempts to kill the firmware, and it'll go
into a pretty mu… ch dead state once we do that. However, if it
times out, then we'll attempt to dump the firmware to be able
to see why it didn't respond. During this dump, we cannot treat
it as if it was still running, since we just tried to kill it,
otherwise dumping will attempt to send a DBGC stop command. As
this command will time out, we'll go into a reset loop.
For now, fix this by setting the trans->state to say firmware
isn't running before doing the reset handshake. In the longer
term, we should clean up the way this state is handled.
It's not entirely clear but it seems likely that this issue was
introduced by my rework of the error handling, prior to that it
would've been synchronous at that point and (I think) not have
attempted to reset since it was already doing down.

You should use ubuntu-bug linux to report this problem to the kernel team, so they can make sure the next iteration of the 6.14 linux-generic update will contain the fix, also mention in the report that you used the mainline test kernel to prove it works…
Please also take into account that the mainline builds are highly insecure, unsupported and do not get updated ever (once you installed it, you are stuck on that version forever) and use the wrong defconfig lacking a lot of config options expected by an Ubuntu userspace, so apps might mis-behave in unexpected ways (as mentioned in the Ubuntu kernel team wiki) you should not use them in production.
