Hi there,
First of all, sorry for the handwriting in the image below… wrote it very quickly. I recently installed a secondary router to work with my Quest 3 VR headset (so I can basically stream VR games wirelessly from my PC). This has a different network name and password. My PC is connected to it, along with my Apple TV, PS5, and Nintendo Switch. The thing is my Jellyfin media server is connected via my main router, which like I said before, has a different name and password. I can’t have my Apple TV or my PC connect to the media server. I also can’t connect from my PC to the media servers via Windows remote desktop, which I also strictly need. Any thoughts how I could fix this? Thanks!
Right now your secondary router is running an entirely separate network than the first one. Depending on the feature set of your main router, you could create a subnet for your secondary router and put it in AP mode, so it doesn’t create the second network and instead acts as an access point to the first one.
