The ethernet side is likely not your issue. Are there any other Aps in the
area (different company perhaps?) or any other device that may cause radio
interference? Is your radio channel plan designed well? It may be that you
need to go wandering around with a wireless sniffer (YellowJacket or Fluke)
and determine what issues are happening in the ait around you.
Isn't wireless fun? :)

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
