Problem with "TC/IP not enable for this connection"

I'm struggle with its Dell Wireless 1450 Wireless USB Adapter. In the XP Device manager, it appears working just fine. But no wireless connection is made with my upstair wirless router, which it has been connected to for 2 plus years. When I attemped to repair the connection, the following on screen message appeared:
"Window could not finish repairing the problem because the following action cannot be completed:
TC/IP not enable for this connection. Connot proceed."

I tried to uninstalled, then, installed it again. But nothing improved...
What should I do?
