I've been having a frustrating issue with my desktop's WiFi connection ever since I switched to Kubuntu 25.04. My setup includes an ASUS Prime X870-P motherboard with built-in WiFi (MT7925E). Initially, everything seems fine after booting, but about an hour in, my WiFi starts having problems. It drops to zero download speed every 10-15 minutes, even though it still shows as connected. When I ping, I get 100% packet loss during these issues.
I didn't have these problems running Windows 11 or Pop!s, so I'm convinced it's something to do with Kubuntu. I've tried a lot of potential fixes, including reinstalling the linux-firmware, disabling power-saving features, and turning off the UFW firewall and IPv6. Despite all this, the problem persists. My router is a TP-Link Archer C80, and while my other devices are fine, this one keeps dropping. I've seen suggestions about switching to a newer kernel (6.15.8), but I'm hesitant to try that as it seems complicated. Any suggestions on what else I might try to resolve this?

It might help to check if your WiFi issue occurs during specific activities, like gaming or streaming. Sometimes performance drops can be linked to network traffic. Just curious, does it happen randomly, or do you notice it more during certain tasks?
If the problem continues, you could look into tweaking your router settings. Occasionally, issues arise from interference or bandwidth allocation. It might help to change the WiFi channel on your router or even switch to using Ethernet temporarily to rule out hardware issues.
I’ll give that a go! I haven’t changed the router settings since I set it up, so it’s worth a try.
Since you've already covered a lot of ground, I'd suggest checking for any driver issues. Sometimes the drivers for your WiFi card might not work perfectly with your current kernel. You could also try booting from a live USB of a newer version of Kubuntu to see if the latest kernel stabilizes your connection without making any permanent changes.
That's a good idea! I might just try booting from a live USB and see how it performs before making any changes to my setup.
It’s pretty random. I was just watching a stream and on a Discord call when it hit. The stream stopped buffering, and my call dropped immediately.
