One common cause of connection problems for Oculus Quest users is your wifi switching between 2.4 GHz and 5 GHz bands. This will cause a lost connection to Rec Room every time it switches, giving various error codes. Please ensure that you have your wifi locked to one band or the other (preferably 5 GHz). If you need help with this, please google "Lock [your wifi device] to 5 GHZ instructions".
Another reason for common disconnections when playing with an Oculus Quest device is due to being too far away from your router, leading to a poor connection. If you're able to, please try and play closer to your router for the best experience.
Please let us know if you're still having connection issues after following these steps!
