Intel Wireless/PRO connection failure

[jack20 0]

Tks for yr help in advance.

 

My Acer290 suddenly experience, on startup, a wireless connection failure this morning? It was working fine for 2 years!

 

The properties window of the Wireless/PRO 2100 BC adapter show it is working fine.. and the suspected corrupted driver w70n51.sys (ver 1.1.6.0) was re-installed successfully.... but still failed to connect. The WZC service failed to start although the RPC and TCP/IP stuff are nicely in place.The D-Link router has no problem.

 

I doubt the winsock is bad, as I could connect to Internet via cable LAN.

 

Apprepriate any advice.
