I have a space where there are three wireless access points installed, all running 802.11n. They all broadcast the same ssid. I think the intention is that the inhabitants and visitors should be able to walk between buildings while their netbooks and ipods happily choose their closest access point.
The problem I have is that people are complaining that they cannot keep a viable signal. It seems likely to be interference to me, but I don't know much about 11n. With a 802.11b network, I'd adjust all the channels to be different and see if that helped, but it doesn't seem to apply to the 11n routers I'm looking at.
The same problem where the signal get lost (network monitor reads disconnected) and then reconnects a few seconds later and cannot communicate with the router (no DHCP) happens with a Windows netbook, a Windows 7 PC, and a MacBook Pro, so it isn't just my machine.
It could be that just one of the access points is flaky. I'm trying to test that now but there's no documentation about exactly where in the building they're hidden.
I'd appreciate hearing about the best practices in managing a network like this, though. I'm not finding much information in the manuals and on the net about how this works with 11n.
