My 3800 is mounted on a (concrete) wall, just below ground level in my basement. I have good 2.4Ghz coverage in my bedroom, two stories up. (This is constrast to the 54gl I used to use, which was above my TV in the den, but it was just an AP-router. My 3800 is next to the 24-port switch, and the DSL modem, since it does everything. Another 3800 is going into the attic, as soon as I dig through the insulation to run cables) As for having identical ESSID on the same layer-2... I think that perhaps cerowrt/openwrt/homenet should consider a wireless AP discovery attribute in the routing protocol, and given that, run GRE over IPv6 ULA between APs. -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | network architect [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails [
