How could it possibly be interference? The roku box sits about 3" from my router. And if that were the case, then why would the other 5 wifi devices in my house continue to work perfectly during this interference? My setup hasn't changed in 2 years, and the only delta that I can see is the most recent firmware update. I'm curious as to why the general consensus around here seems to be that it's my fault or my setup, even when I see other similar posts?
Because 8 out of 10 of those threads, those users solved the issue by either changing the router channel or moving the device. Sitting that closely to your router, even the router itself can emit interference. I've had personal instances when the Roku in my living room, sitting within 6 feet of my router, would not connect due to interference from either my computer or BLu-Ray player, yet the one in the bedroom (about 35-40 feet away) could connect flawlessly. And even then, my iPad wouldn't connect.
All of your symptoms point to an interference issue. It would be a very rare instance that the wireless chip in the unit is suffering failure. I've been with Roku for over a year now, and have only seen two instances of that happening, three at worst.
