Wireless PCs Unable to Access Ethernet-connected Resources

I am experiencing a problem on a home network after installing a Wireless Access Point/Router, with wireless PCs being unable to access (or ping) resources on ethernet-connected machines and vice versa. The network is configured as follows:

Internet connection via Starband 5.1/WinProxy 5.x on dedicated PC running XP (90.0.0.1).
Starband PC connected (CAT5) to LAN through a Gigafast switch.
Several client PCs (all XP) also connected (CAT5) to the switch (90.0.0.2 - 90.0.0.10, Static).
Gigafast WF711-APR WAP/Router connected to the switch with a CAT5 crossover cable.

WAP/Router parameters, by configuration section:

WAN
WAN IP Address: 90.0.0.50 (Static)
WAN Subnet Mask: 255.255.255.0
WAN Gateway: 90.0.0.1
WAN 1st DNS: 139.175.55.244

LAN: I have enabled DHCP (90.0.0.60 - 90.0.0.70) and also disabled it and assigned Static TCP/IP parameters. The mode it's set to didn't make any difference; internet access okay, but LAN functionality nonexistent.

ACCESS CONTROL
Response to Ping from WAN - Allow
Web Management from WAN - Allow      Port: 54321
Block Client in LAN - Disable
Fileter Packets from LAN - Disable

SERVICE TIME: Normal

URL BLOCKING: Disable

VIRTUAL SERVER: Disable

DMZ: Disable

AUTO 2-WAY APPLICATIONS: Disable

DYNAMIC DNS: Disable

Both cabled and wireless PCs are able to access the internet, but the wireless PCs are unable to access shares, ping or communicate in a high level manner with any hard-wired resources. Likewise, the cabled PCs cannot "see" any of the wireless resources or devices. The wireless PCs can see each other. Internet traffic is obviously being routed from the WAP through 90.0.0.1, but wireless PCs are unable to ping it or map a drive on it. All of the PCs (wired & wireless) which have static addresses assigned are in the same workgroup, and also have the same subnet mask and gateway as defined on the WAP/Router. I have temporarily disabled firewalls on all of the PCs and also attempted to set the WAPs least restrictive parameters to eliminate those things from the equation.

Can the wireless PCs can be made to operate on my LAN similarly to the hard-wired machines, i.e., access shares, map drives, etc.?

Are you connecting the WAN to a LAN port on the AP, or the WAN (internet) port?
try connecting to a LAN port
