Try a channel between 8 & 11 to find which gives you strongest signal and least amount of cut-offs.
Low channel numbers (ie below 8) are usually less stable than higher ones.
Bear in mind that the factory default setting for channel selection on most routers is "Automatic" and that's where many users leave them, so the channels in use in your neighbourhood will change several times a day. That fact really makes your neighbourhood WiFi channel list pretty irrelevant.
