Hello. I have Quest 3. And I cannot link it to Steam with a new router by WiFi.

I had some old Keenetic router that was pretty weak for VR but at least had no issues to connect. And now I've got (as a gift from friends) a new one, Cudy, with a newer WiFi but run on OpenWRT which I have almost zero knowledge about... So I need a help with any ideas where to look the problem...

And the problem is that SteamVR doesn't think my Quest 3 is placed into local with my PC.
PC is connected by lan cable. Quest 3 is connected by WiFi. All lans and WiFi are united into a bridge with incoming internet by cable to wan (so WiFi and Lan actually ARE in local network).
I have successfully connected to Skybox video player and play videos from my PC (the only issue there was I had to type in local IP by hands). I can use Air Link to Meta. Works a bit slow but works, can even launch some games like VRChat. I can even launch SteamVR from Meta Link (but that is fiasco because Meta allows just 200 mbps max in options). And still... no direct Steam Link. Has someone any ideas where to look at least?

Thanks for those who've read this whole sheet
