I want to cover a wide area with several access points wired to ethernet LAN but am confused by different articles/manuals. Some say that to maintain a mobile connection you need each access point on a non overlapping channel (1,6,11) and with the same SSID and encryption. Others seem to say that all the access points must be on the same channel or the connection will be broken when the client switches between them. Won't they just interfere with one another if they are on the same channel? Any pointers to relevant documentation?
