Ubuntu 25.10 recently begun dropping WiFi connection

[letter3770]

Ubuntu Version: Ubuntu 25.10

Desktop Environment (if applicable): GNOME

Problem Description:
I have been using Ubuntu 25.10 for a few months and only in the past 1-2 weeks my WiFi connection has begun frequently dropping. Sometimes it’ll show I’m still connected to WiFi but I clearly cannot use the internet (I can’t perform searches and my connection to a call either drops or they can hear me but I can’t hear them). Other times it’ll show that my WiFi connection has completely dropped and I end up having to “forget” and reconnect to my WiFi network.

Connection issues occur more often while I’m connected to a VPN service. My network seems to work fine as I never have issues with my Android in the same room. I’m unable to test with other WiFi networks or switch to a wired connection at this time.

Relevant System Information:
ASUS Expertbook B9.

Wireless-info diagnostic tool output: https://privatebin.net/?34e612ead34d748d#g3ULyw63BgXfo8Kj97TFfzJc8ryqw7WKDCiWYYv1PdQ

What I’ve Tried:
Performed system updates.

Have you tried a router reboot?

Can also try

echo “options iwlwifi power_save=0” | sudo tee /etc/modprobe.d/iwlwififix.conf > /dev/null

Reboot to test. If it’s no better then run:

sudo rm /etc/modprobe.d/iwlwififix.conf

Then reboot again

I have the same problem after upgrading. My router is actually placed next to the laptop. Mine is Lenovo LOQ 15IAX9, Intel^® WiFi 6 (802.11ax)
