Slow wireless with XP 64bit

I'm running an evga 750i mobo and XP Pro X64. I have an Asus 138g v2 wireless card. I got the correct x64 driver for it from Asus's site. But it is slower than dial-up. When I plug in the ethernet cable this computer runs faster than Superman. On the wireless it is so slow. I show 54 mbps and excellent signal strength. I have checked security settings, connectivity, opened both 64 and 32 bit IE pages, and the card itself. The card worked awesome in my old WinXP box. I re-installed the driver and no difference. The card was seated properly too. Is it possible my OS and/or mobo just don't like wireless, or my wireless card?

The network is good, as my laptop never has a problem.
