Low speed in wired local net for Steam Link and Moonlight
I have a PC (connected to the router with a 1 Gigabit cable) and an android tablet connected to the router via a Type-C hub and a 100 Megabit cable. When I check the speed of the local network between them using iperf3, it shows me a speed of about 100 megabits. But when checking on Steam Link, the speed shows around 25-30 megabits. Moonlight+Sunshine has the same problem. If you connect the tablet not with a cable, but via wi-fi, then the speed is around 70 megabits, which is already normal.
I've tried 4 different USB hubs and the problem repeats. I also tried changing the 100 megabit cable to 1 gigabit, it doesn't help.
But then I tried to connect it via another router and everything works fine there!

Hello @GT21 ,
Welcome to our community.
Could you tell me the model numbers of your tablet and USB hub?
- For the USB hub, please confirm it supports Gigabit Ethernet. Please try a different Ethernet cable for comparison.
- Please verify that the negotiated speed on the router's LAN port for the tablet is 1000 Mbps.
- Please ensure the tablet's wired link speed is 1000 Mbps. How to check the associated/link speed on a wired client.
- Please ensure the tablet supports USB 3.0 or higher.
- If possible, test the USB hub on a different wireless device.

@Joseph-TP The problem is not that I don't have 1 Gigabit. The problem is that I don't even have 100 mbps. When I check the broadcast through the Steam Link, it shows only 20-25 megabits. (there is a similar problem with speed in sunshine + moonlight. But the specific speed is not displayed there, it just says reduce the bitrate, although I have it set to 15 megabits). But when checking the speed through iperf3, the speed is about 80-90. Moreover, I tried to connect via the xiaomi router, and there is no such problem.

@Joseph-TP Yesterday I tried to flash the router to a previous firmware version, disable upnp, and disable everything in the ALG section. None of this helped.

@Joseph-TP And one more thing: I tried 3 other usb hubs before that, this is the fourth one. It's the same problem everywhere.
