John - Why are you using ad-hoc? The normal way to create a wireless
network in a home user situation such as you describe in infra, not
ad-hoc. Of course, I'm not at your house so I can't see what you're
doing, but you should not need to create a bridge. For instance, I have
a wired network using a Linksys 8-port wired router. To that, I've added
a Linksys Wireless Access Point and another WAP (to an XBox). The WAP
isn't a bridge - everything is on the same subnet. If you don't have any
wired component, the setup is similar: you would have the wireless
router, no additional WAP's, just the pci cards in your various boxen or
pc card in a laptop. All boxen would get their ip addresses using dhcp
from the wireless router, which would not be set up as a bridge or
ad-hoc, but with the infrastructure option instead. A bridge is meant to
connect two separate subnets, which you don't want to have in your
setup.
