There are a couple of pieces of information that would be helpful in
troubleshooting just about any network issue:

1.  The make, model, and version numbers of network components involved --
in this case, the router and the WAP.

2.  The output of running "ipconfig /all" and "route /print" on
  a) at least one working cliemt, and
  b) the non-working client(s)

3.  Any DHCP and NAT configuration on the network.

4.  Ping results between various components.

  Any of these might contain vital clues as to what is failing where.
