Hi, I've even gone as far as a complete factory reset but nothing is working. All other devices in the house are fine but suddenly the Roku stick is dropping the wifi connection constantly (ie every 5 minutes or so).
The stick is literally 1m away from the router.
It has gone from being the most convenient streaming stick we've owned to the most frustrating, almost overnight.
You can also try configuring your router and use wireless channels 1, 6, or 11 which are the preferred channels in North America. Each time you change the wireless channel, you will likely need to apply/save changes before you are prompted to restart the router.
