problems with a TP-Link wifi adapter

[chermany4ever]

Hello guys. I'm having problems with a wifi adapter. It's the TL-WN8200ND v2 that I bought especially cause it works with XP but I can't make it work. I was able to test it in another PC that has Windows 7 and it works fine. Has a lot of reach and I can make the most of the 5mb connection speed. Thought about buying it cause the prior one I have that works in XP is also a TP-Link but one of those little ones that doesn't have great range and since I'm far from the router the only way to navigate was sharing the wifi signal from the cell phone -which does see the signal- and though I manage to navigate my speed is limited to 1MB. When I plug the card at the USB port the light turns on but when installing the drivers the system fails to communicate with the card. I don't know if it may be a conflict with the old drivers of the little card? Thought that cause wanting to go back to the old card I couldn't, even when uninstalled everything that had to do with the new one, so was forced to return to an image of my system. Also thought perhaps the problem was that I used SP2 so I tried to install XP SP3 to check but it didn't work either. Any ideas?
