I recently bought a D-Link DWL-G510 Rev C2 wireless card. It's installed in my desktop PC running Vista Ultimate. It has had its ups and downs, so I'll explain...
Installed the card and used the Vista drivers from the D-Link website. Seemed to work fine, but then I noticed my download speed was very slow (normal speed around 400-500kbps, slow speed around 100-150kbps). I fixed this by using the XP drivers on the site.
Everything was running smoothly up until now. The connection keeps dropping even though the signal strength is either very good or excellent. When the network is connected the speed as very bad. I checked on a speed test and the speed was similar to 28.8k dial-up (
). Also, if Vista sees the network it will try and connect but then fail saying "it has failed due to an unknown reason". Obviously this makes using the internet very difficult.
I tried uninstalling the drivers and installing the Vista ones, but no go. Same thing happens. Try different variations (Rev A, or B drivers as well as XP and Vista ones) and I even tried the RaLink drivers (as they use the same chipset and D-Link just re-brand them)
It is really frustrating. Any ideas?
