meta quest 2

Im a noob to vr and wondering if anyone else had this issue, might be something i am doing, or it may just be how it is So im getting a used quest 2 for christmas from the mrs, already have it and the mrs allowed me to have a night to play and test it :D i followed the guide to get it set up...

hi, recently got meta quest 2 from Ocuk, but i bought a google chromecast device to cast the vr to the tv when gaming and even though the chromecast is on 2.4Ghz WiFiand my vr meta is on 5ghz it still drops every few mins, longest its been connected is 6 mins :( . i have no idea what im doing...
