Deminished BW using WAP v. Wired through a WRT54GC

Hi,

I'm at a loss as to why I get such lousy throughput on my WiFi.

I used NetCPS to test the throughput.

Both computers are within 10 feet of the 54GC and I have about a -35 dB signal with -85 dB of noise.

The first part below symbolically shows my network configuration.
FIOS to a router (theirs), to another router (mine) to a 10/100 switch to the WRT54GC and to a 10/100/1000 switch
The 10/100/1000 switch goes to two computers (a P3 and a P4), the 54GC goes to two laptops (Celeron and a Pentium M)

To compare, I tested the Pentium M both through the WiFi and through the wired connection on the WRT54GC.

As you can see the wireless is horrible compared to wired.

Any ideas why it's so bad?
