Dunno about the rest of your list, but I have successfully set up multiple access points with roaming by using VLANs between them. Of course VLAN-aware switches help, but if you have the access points connected directly via a wire, you can use the VLAN support in openwrt, to basically bridge the wifi interfaces of the two access points. That way you avoid the problems with broadcasting across the LAN/WLAN border, but can still get roaming on the same IP subnet. You'll want to have one access point running DHCP, and the other just being passively serving as the access point. This can be setup via openwrt config files; can share my config if you're interested. > It appears a lot of 'it just works' functionality is designed for > bridged LAN/WLAN scenarios and hates routed but maybe I've got the > wrong end of a stick. For some things, having the reflector functionality of avahi-daemon turned on somewhere it can see both subnets helps on discovery and 'just works'-iness :) -Toke
