Title:
Wifi randomly disconnects [AR9462]

> Is the workaround of using an older linux kernel working ?
I'm using without problems the 5.15.4 (that is not older but newer than
the 5.15.0 installed by 22.04 but is "old" with respect to the
development lines 5.15.x, 5.16.x etc... )
to known your version, open a terminal and type
>uname -a
Exactly the same issue here, upgrade from 21.04 to 22.04 made wifi
connection unstable and unusable.
I have a Asus N55JK Laptop with Qualcomm Atheros AR9462 wifi adapter.
No issue with the network or when I'm using ethernet.
Is the workaround of using an older linux kernel working ? I'm new to
a) could somebody point me to some page with the information on how to
install and build the official Ubuntu Kernel ? (address of the
repository and instructions to build/install it)
I plan to bisect from 5.15.4 to 5.15.5 to try to catch what is causing
the problem
It was suggested to do that
I installed the official 5.15.0-32 (via >apt install linux-generic)
released in these days and it also contains the problem
Linux ubuntu 5.15.0-32-generic #33-Ubuntu SMP Tue May 10 08:40:25 UTC

I tested with kernel 5.18.0rc5 which also shows the disconnection problem
For testing 5.18.0rc5 I desinstalled the NVIDIA driver and removed the
NVIDIA files which excludes that element from the suspects list
