I have a continuing perplexing network issue in a large home with multiple wireless access points. I've installed a router (Dlink DIR 855 in the basement, rear) and using 2 Dlink powerline adapters, an access point (a Netgear 300mbps model in a second floor closet). The router and access point are set to static channels 8 numbers apart, and share the same sid and passcode. The house has newer construction, so I believe the wiring is up to snuff.
The issue is that the users have to now disconnect and then reconnect to the network regularly. My understanding is that different channels and the same sid and passcode was supposed to be seamless. The users are not passing out of range when this happens.
