My router has nine different wifi channels for 5gigahertz. I tried all of them. A couple gave 3mb and the rest 5mb. Is it possible at this point that I might have a faulty roku? I bought it off of Ebay.
9 channels sounds strange since there should be at least a few dozen. Have you given any of the 2.4GHz channels a try?
The nine 5 GHz channels supported by Roku devices are 36, 40, 44, 48, 149, 153, 157, 161, and 165.
The other channels assigned to the 5 GHz band between 49 and 148 are shared with other uses such as military, radar, and weather. These channels are termed DFS (dynamic frequency selection) and routers are supposed to automatically switch to a different channel if they detect one of these channels is in use in your area. Roku devices don't support these DFS channels and some home routers don't even include them.
