Your guess is good as anyone's. D-Link makes subpar wi-fi equipment, in my opinion.

I looked into their PCI wi-fi card, the DWL-520 and 520+. After doing a search for problems on the internet, I discovered that:

1. The D-Link PCI card is incompatible with a Soundblaster PCI card, so it's one or the other.

2. The D-Link card causes Windows XP to fail to boot, unless it is removed, in certain motherboards.

I compared this to a Netgear wi-fi card, and the only complaint I could possibly find about the Netgear card was some thing with Linux OS.

I stay away from D-Link equipment.
