Steam Link App: 'Slow Connection' with wired PC > Router > Mesh Router > Nvidia Shield TV
I had this setup working previously (flawlessly) with zero controller/input lag with a wired ethernet connection from PC > Router > TV (Nvidia Shield TV with Steam Link App). We have 2 high end PCs so I wouldn't count that in the equation.

The new twist in our current house is that we're running direct ethernet to the main router and then a direct ethernet connection to a mesh router in the basement (Asus RT-AX86U Main > Asus RT-AX55 Mesh > Nvidia Shield TV). We've had zero problems steaming or doing anything else (I have a Synology with Plex server running the same route with zero issue), and the steam link works on the TV, but it always says 'Slow Connection' and we've got that 1/4 to 1/2 second input lag on the Xbox Elite Series 2 controller... and my main theory is that it's because I'm running through two routers.

Can anyone confirm this as a possible issue, and ideas to remedy? My current thought to troubleshoot is to wire pull another freaking ethernet cable straight from the PC that's streaming on our 1st floor downstairs to the basement straight into the mesh router or the shield tv itself which will be a pain in the butt (but maybe necessary in this scenario).

All router settings are pretty standard - the primary router is powerful enough and doesn't have enough activity to bottleneck... so here we stand. Thanks for any advice or insight.

tvs only have 10/100mb (fast) network port, not 1000mb/s (gigabit)
if the tv is 4k, it does not have enough bandwidth on its lan port for a good quality stream

lower its streaming res to 1080p, either on client or host
steam -> settings -> remote play -> [advanced client options] -> resolution limit = 1080p

also how are the routers connected and configured?
how fast is your internet upload/download?

2nd router should be in switch/bridge mode
turn off its dhcp server, and do not connect anything to its wan/internet port
so it does not try to work as a router, and only as a switch/client/ap
and disable lan/wifi isolation on both routers and the wifi ssid you use

then all devices connecting to either router will all get the lan ip from the main router, and be able to talk to each other

I’m not running to my TV - I’m running Ethernet from a pc, to my primary router, then another Ethernet to my basement mesh router, and then another direct Ethernet to an *Nvidia Shield TV Pro*. That is where steam link app runs and then sends to my TV though HDMI.

Second router is in what I suppose is bridge mode as it’s using ASUS’s mesh enabled feature. The not connecting anything to its wan/internet - maybe I’m confused - doesn’t that mesh router need to receive its internet to that port from my primary router? I didn’t think plugging an Ethernet line from my main router out to one of the normal numbered ports on the mesh router would do anything as far as providing it internet.

Everything should be setup pretty normally as a wired router to mesh router - I wrote the full chain and router models in my original post above. Maybe I’m misunderstanding something.

its mesh mode might just work as repeat/extend

check the ip of the client, nvidia shield (should be 192.168.same.different)
and make sure you can ping it from the host pc
that will verify its on the same subnet, and some ports are not blocked by the routers wifi firewall

also make sure windows network is set to private not public, as that will block steams streaming ports from connecting to pcs on the same subnet

those set wrong will force steam to use internet relays, and your internet upload+download , instead of just lan/wifi traffic
