Having buffering issues on WiFi on both my Ultra 3 and weak signal on my laptop. Replacing the Ultra 3 with my old Roku 2 makes the problem go away, getting greater that 100Mbps. Got a WiFi analyzer for my phone and I see an unnamed channel right on top of mine no matter the channel only with the Ultra 3. I assume this is for the remote. Why is it on the same channel? That seems so obviously bad. Is there a way to fix this?
Re: WiFi from ultra 3 overpowering my access point
Yeah, this is really an old topic. I have no idea why it affects some but not others. I believe the remote must be on the same channel as the Wi-Fi connection since there's only one radio. There's no such thing as an "Ultra 3", so I assume you either have a Roku 3 or an Ultra. Either way both models support a wired connection. I'd suggest you go that route, but you could also try both 2.4 and 5GHz and see if one is better than the other.
