Netgear wireless adapter problems

Hi there, I wasn't sure whether to put this in the networking or driver section so please excuse me if I've posted it in the wrong one.

I recently got a Netgear wireless adapter, model WG111v2. When I first installed it, it worked fine for about a day then suddenly internet pages would either load incredibly slowly or not load at all. The problem affected both Firefox and IE. I uninstalled and reinstalled the adapter and it started working fine again, for about another day, then pages wouldn't load properly again. I now reinstalled it for a third time and it's working again but I suspect that pretty soon I'm gonna have the same problem. Could you please tell me what I should do if this should happen?

My PC is a Packard Bell IMEDIA 1559.

I used Everest Home Edition to try to get the details about the motherboard but I was a bit confused as to what I was looking for, so here's all the info I think may be relevant.

Motherboard
CPU Type: DualCore Intel Pentium D 820, 2800 MHz (14 x 200)
Motherboard Name: Unknown
Motherboard Chipset: ATI Radeon Xpress 200
System Memory: 1024 MB (DDR2-533 DDR SDRAM)
BIOS: Type Award (05/19/06)

Any help is greatly appreciated. Thanks.

Sorry I forgot to mention that while loading of all pages is incredibly slow/not working, that I still have a full wireless signal.

 

Hey again, I turned off the power saving option but after a day of use the same problem occurred. And now theres another problem, which is that the driver won't uninstall. If I try to uninstall it from "Add or Remove programs" it runs through the uninstallation procedure but after it the program is still there on the list. If I try to delete it from the Program Files folder it says its not allowed.
For some reason the internet is running fine again right now but I don't know for how long.

To answer your previous question I'm using Windows XP Home Edition Service Pack 2.

Also there may be another potential issue. Before I got this Netgear adapter I was using another Netgear adapter which was also a WG111 model but it was V3 not V2. I thought I had uninstalled all of it's files (after finding out the driver for that version didnt work on the newly bought one) but I've found a folder named "WG111v3" in C:\WINDOWS\inf Is it possible that there are files left over from the previous adapter that are causing problems with the new one?

It's all gotten a bit confusing so I hope I've managed to explain the situation well enough. Any info/advice would be great.

 

Thanks for the links

Do you think its safe to delete C:\WINDOWS\inf\WG111v3 ? I really don't know what it is or why it's there
