Wifi drops randomly - Qualcomm Atheros - Ubuntu 25.10

Ubuntu 25.10, GNOME, Dell XPS 13 9380

Wifi has been dropping randomly for the past year. Sometimes it bogs down the entire system. I think it happens more with 5GHz networks. It got so bad that I’m using an ethernet cable, but I’m determined to find the cause and fix it. Help, please?

I tried the Network Connection Troubleshooting script and this is the output:

I’m ready to dig deep into this. This laptop has worked flawlessly for years, and I’m not giving up on it.

Thank you!

Anyone? Anyone? Bueller?

Are you seeing anything in your dmesg or journal entries when the 5Ghz drops? I would search something like.
sudo dmesg |grep wlp2s0
or
sudo dmesg |grep iwlwifi
Or check /var/log/syslog for errors and the like
Also look into journalctl entries for errors.
Try to isolate what the logs are showing.

What is the output of:
sudo lshw -C network
Thanks
