Networking issues (desktop mode)

Submitted ⁨⁨12⁩ ⁨hours⁩ ago⁩ by ⁨khannie@lemmy.world⁩ to ⁨steamdeck@sopuli.xyz⁩

I mostly use the deck in desktop mode recently as my laptop died and I have it hooked up to a dock with monitor and keyboard.

I’m having a bunch of networking issues lately. Basically the network becomes incredibly unstable after some time and a reboot fixes it. Restarting networking through systemd does not fix the issue. Same with disable / enable networking in the dropdown.

Ping is going as high as 10,000ms where after a reboot it’s 14ms and I’m getting 5-15% packet loss.

The router is about 7 metres away (22 feet or so).

I do suspend quite a bit. System is fully up to date. Just rebooted and now it’s fine.

I’ve had this issue with a crappy monitor. Whenever I plugged my laptop into the HDMI cable to that particular monitor, the WiFi practically died. I think it’s because the cable or the monitor acted like an antenna, but a properly shielded cable shouldn’t be doing that anyway, so who knows what the culprit is. All I know is it was either the old monitor or the cable itself.

I’d start by slowly excluding the hardware one by one. It you’re using some third party dock, that dock could very well be the reason why the WiFi dies.

Holy. Fucking. Shit.

This was it.

Here’s my ping output. You can see where I unplugged and replugged the HDMI cable. Absolutely not in my wildest dreams would I have thought of this. Thank you so much.

I would recommend disabling wifi battery optimization. I know you can do it from settings in game mode, I’m guessing there may also be a KDE setting for it.

  Thanks. I can’t see it in the KDE settings but will give that a whirl.

Are you using it via cable or wifi?

The official dock or 3rd party?

Even with the reboot, it could still be that the IP is renewed, it would help if you could find out how frequently it happens. What kind of router are you using?

Have you been keeping the OS up to date?

source
- khannie@lemmy.world ⁨11⁩ ⁨hours⁩ ago
  It’s WiFi, 3rd party dock (but deck WiFi), ISP router which is unaffected on other devices, OS is right up to date.
  
  I did reboot the ISP router just before posting and the issue still persisted until I rebooted the deck at which point it was gone.

    Can you test if this happens when you use a network cable or does your dock not come with a network port?
    
    Do you know what wifi does your ISP router use? Is it 5 or 6? Is it set to 2.4, 5, or 6Ghz?
    
    How far is it from the router? Does any other device drop connection?
