Thanks for the response Scott.
The switch ports are set to full duplex, as is the router. I tried putting
the switch ports down to half duplex, and I got about 3Mbs of download
speed. As far as interference, the APs are dispersed throughought a 9 Story
building. I was thinking that one may be getting interference from an AC or
something like that, but they are all responding in the same manner.
Thanks,
Boris
