[TRACKING] WiFi drops out (especially when downloading a lot) but fixes instantly by reconnecting (AMD)

Nope, it’s all the same, glad you have a working laptop! I love computers.

Recommend you pin that image for a bit and see how it handles over the next few major kernel upgrades as they come down from Fedora.

Running into somewhat similar behavior on my AMD 13 with both the Mediatek card and Intel 210. General behavior seen is as soon as download bandwidth usage increases (upload seems unaffected), latency goes through the roof, speed tanks.

Steps to reproduce:

  • Run ping to 8.8.8.8
  • Start speedtest (i’m using speedtest.net)

Symptoms: Download speed will pick up as normal then completely stall out, ping latency will spike to several seconds while this speed crash occurs.

Tested on:

  • Ubuntu 24.04 (installed)
  • Ubuntu 23.10 (live usb, no updates)
  • Ubuntu 22.04.4 (live usb, no updates)
  • Manjaro 24.05 (live usb, no updates)

Network is configured so band steering is disabled, network is 5ghz only, single AP (Unifi A6 Pro).

So with my Eero 6E setup, two mesh router updates later and it has not been a problem since at my home office. Bazzite/Bluefin, Fedora and Ubuntu. I’d need to see output from this being run to know for sure if this is the same thing, as it would catch a frequency change (even if you believe it’s disabled, I’ve seen routers not actually do it).

In my case, at the time, it was poor handing off of 5 to 6 ghz.

Also worth grabbing journalctl --since "2024-05-16 13:50:00" --until "2024-05-16 13:58:00" (adjusting the times to match your occurrence) to see if anything new jumps out. Often times nothing does, but sometimes it can. VPNs that folks forgot about that are installed, etc.

Do you need the log files or just the console output?

If it’s just the console output here you go:

iw is already installed.
lshw is already installed.
