Hello, I need to report a bug in K/Ubuntu 26.04 running on a Dell Inspiron 2350.

This PC runs fine with K/Ubuntu 25.10 and previous versions, but when I try 26.04, the wifi adapter will drop after a few second, then connect again. The cycle repeats.
A popup on the screen reads:

Network Management
Wireless Interface (wlp4so)
Authorization supplicant timed out.

I tried to file an apport when I ran ubuntu-bug but the connection problem won't allow it.

The wifi adapter is a Qualcomm Atheros QCA 95565/AR9565 wireless adapter. The kernel driver is ath9k.

I tried running a few commands when I researched the problem in https://launchpad.net/ubuntu, but didn't see one posted for 26.04.

Again, this runs fine on Kubuntu 25.10 and previous. Could this be a Linux 7 issue?

Any help would be greatly appreciated, and thank you in advance!
