[Q] Chromecast setup problems. topic

So, I'm setting up my new chromecast, but have have run into a problem. I'm able to find and connect my phone/PC to the chromecast itself, but it won't connect to my home (setup hangs at "connecting"). After a while I get an error message a la "can not establish contact with chromecast" (roughly translated from Norwegian). I've made sure uPnP and MAC address filtering both are disabled on my router.*I've already tried factory resetting the chromecast and moving closer to the router, to no help.

Worth mentioning is that my router is not exactly new (tilgin vood something), and is not to be found in the list of routers in the chromecast support section.*

Any tips?
