I have a gawd awful D-Link DWL-G520 PCI supposed fast wifi NIC.
Apart from all the BSOD's, I just cannot get it to work with the Netgear DG834gt router at 108mbps.
I have turned on the error reporting in the Activty section of Network properties(regedit key to get this), and I have an awful lot of errors, even at this slower speed.
I even get error when my firewall is telling me the darned thing is not even transmitting/receiving.
