Windows Cannot Configure this Wireless Connection

I have a Windows XP laptop and everything was working fine before its wireless adapter stopped working and I had to have another one installed. The technician who installed it was able to get the wireless connection working but after a few days, whenever I try to connect to the wireless network, I get an error saying "Windows Cannot Configure this Wireless this Wireless Connection."
The technician taught me how to start the Wireless Zero service from the Services window and to check the option that says "Use Windows to configure my wireless network settings" on the Wireless Networks tab inside the Wireless Network Connection Properties window and it usually works after I do these steps but if I restart my computer, it gives me the same error message again and I have to do the above steps all over again before I can get it working.
It's really getting so annoying already. Please help me.
