Fire TV only supports channels 36 to 48 at 5 GHz. If you use a channel between 52 and 140, no connection can be established. Amazon does not offer the higher 5 GHz channels because of the cost of DFS certification required for channels 52 to 140.
DFS means Dynamic Frequency Selection, which is a technology that makes it possible to detect when they are interfering with military and radar systems and automatically switch to another frequency to avoid interference.
