Ethernet connection cut to a third when connected to exclusively to a dock

Laptop: Framework 16 Ryzen™ 7 7840HS
OS: Windows 11
Network Layout: Ethernet wall > Router > Switch > Dock > FW16
Issue: When I have that set up, my FW16 gets around 300-315 Mbps.

What’s ruled out:

  • I plugged my FW16 directly into the wall, router, or switch and I get 800-900 Mbps.
  • When I plug my Steam Deck into the dock or another laptop, I get the usual 800-900 Mbps.
  • I’ve reinstalled the driver update and the issue is still there.

Does the dock also have video on it? If so, do Steam Deck and the other laptop negotiate the same resolution? I imagine one could lose network bandwidth if a lot is needed for screen. A way to test might be to unplug any monitor from the dock and see what the network speed is then.

I imagine another option could be that somehow the FW negotiates a lower transfer speed to the dock?

With an 11th gen. intel FW13 I’m getting a ~900Mpbs network connection on a USB-C monitor with built-in network interface. That’s a different motherboard, though, so I’m not sure how much that says about the FW16.

Sorry I forgot to mention about the video settings. Using the official framework 16 port diagram, I connected my monitor which is Display Port to USB C to port 4 on the laptop and the dock to port 5. The laptop and monitor is smart enough to know to use the usb c and display port respectively so the hdmi port on the dock isn’t used.

With that being said, I followed your suggestion and it’s still 300.

If it helps, I use a Nintendo Switch power adapter to power the dock and charge the laptop. It had no problems before but sometimes (not always) I can get the speed to return by turning off and on the power strip that the dock is connected to or unplugging the Switch adaptor and replugging it in a different socket (sometimes going back and fourth between two places). I also used a 100W GaN charger on the dock and plugged it straight to the wall and the issues still remain.

Going from close to gigabit to below 400mbit sounds suspiciously like the ethernet adabter may be running at usb2 speeds. Might want to check that.

I think that might be the issue. I had the same thought of it being just hovering around 300 but never went as so far as to think it was usb 2 speed. Thanks!

For pure usb-c+displayport docks there two different lane allocations, either you get 2 lanes for displayport and 2 for usb3 or all 4 for displayport which leaves you with only the usb2 connections for usb (they got their own wires)

Just looking now it says there is a BIOS update that came out last week and it mentions:

  • Fixed 2 performance issues when connected with 3rd party adapters and dongles.

That’s for 3.05 and I’m still on 3.03 I think so I’ll be updating it now. However, I’m still considering your input because it’s mostly a dock problem than a FW problem. When I disconnected the FW and put in something else, the dock might have switched back to usb 3 mode which is why the other devices went max speed on their download test.
