Elvis7,
On a wireless routers, in the g mode as people know it 2.4GHz the best channels are channels 1, 6 or 11. I find the best results are channel 11.
On a wireless N 5.0GHz, it seems different. I was trying to get the information from this article. List of WLAN channels
The article states about using DFS/TPC for less interference. I tried to select channels with all green blocks.
Questioon is there a cordless phone in your home? If yes, when the phone rings, or you use the phone, you get disconnected?
