If D-Link DWL-G630 utility tries to install with Texas Instrument PCMCIA adapter, it will hang up and not finish the D-link registry update. Although your wireless adapter may still work, REG.EXE from the D-link subdirectory will execute each time you reboot, get hung up again, and cause your Win 2000 services.exe to us 90-100% of your CPU time. I removed the D-link REG.EXE from my windows registry and window and DWL-G630 works fine. (further information...)
