Steam Deck Dock Ethernet Stuck at 100Mbps

[marzattaxx]

Hey everyone, I've already reached out to Valve about this but just wondering if any of you with the official dock are having similar issues?

When I first plugged in the dock I noticed that I was getting very slow download speeds (was installing a large game). Peak of ~8-9Mbps. This was pretty consistent, so I thought "okay, for some reason the dock didn't automatically set the ethernet connection to 1Gbps". I found there was no way to check this in Game Mode so I went into desktop mode. Sure enough it automatically set the connection to 100Mbps. So I went ahead and set it to 1Gbps and ran a speedtest; getting a solid 800Mbps. Switched back over to Game Mode and am still running into the same speed problem. It seems it sets the ethernet connection back to auto rather than the manually defined speed.

It's persistent across several reboots and a multitude of CAT6e cables. If I plug the dock into my laptop, it immediately picks up that it's a 1Gbps connection.

Anyone else running into this?

this issue is still present on the OFFICIAL valve dock, pretty sad...

Having the same issue. Other devices run at 1Gbps on the very same wire. Using official "Steam Dock". Ethernet link negotiation was set to Ignore and the speed was at 100Mbps, greyed out. Tried both auto negotiation and manual set to 1Gbps, I can't get the max DL speeds I should be able to get.

Weird thing though: My internet is 100/40 Mbps, so theoretically I should be able to get around 12.5MB/s through the pipe even when the Dock just runs at 100Mbps. But my DL speeds in Steam are capping somewhere around 6-7.5 MB/s. I can do a speedtest in the browser and get what my line provides though.

Edit: *facehoof* - I was "remote playing" System Monitor to do things conveniently from my desktop PC. Disconnecting that stream bought the DL speed up to around 12.5.

That still leaves the thing auto detecting the ethernet at just 100Mbps though and not using more even if manually set to 1Gbps. If I had a faster line (getting actual FTTH instead of FTTC soon™), I'd probably not see higher speeds right now, which should be possible though. That aside, having 1Gbps ethernet, the Remote Play stream over LAN shouldn't take away any of the 12.5MB/s DL bandwith as there's still 112.5MB/s left to use theoretically.

Hello!
I stumbled in this thread recently as I was having the same issue but I was able to fix it with the help of Steam Support.
It seems that sometimes after firmware upgrade the Steam official docking station needs a kick!
This is how I fixed it:
- detach the Steam Deck from the docking station
- reset the DP controller on the Steam Deck: press volume - and ... buttons at the same time for 5-8 seconds until you hear a bip and see the screen flickering, with a bunch of notification of internal devices going down and then up again
- shutdown the Steam Deck then power it on again (DO NOT reset it, you need to shut it down, wait a minute or two, then power it on again)
- remove the power cord from the docking station and leave it like that for 4-5 minutes
- reconnect the power cord to the docking station
- attach the steam deck to the docking station
You should have now the network interface at full speed!
Hope this helps.
Ciao!
