Dlink DWL-520 Wireless Card+DI- Wireless router+Windows XP SP2

Grettigns all,

I have this configuration with 15 pc's running Windows XP SP2, the
manufacturer says that I need to turn of the Windows Zero Wireless Utility
and let the software of the wireless card DWL-520 take control of the
wireless connections, but this I don't know if It working, all pc's be
connected with the router perfectly, Ip's assigned with no problem, but some
pc's have internet access and others not, even two pc's together, one have
internet and the other besides not. I need to get back to the Windows
Wireless Utility?, Anyone use this router and report this type of problems?.
Please Any help will be apreciated.
Fernando
