hello... ready to put a hammer to the laptop! Dell Inspiron/Vista working perfectly until mid dec. Wireless connection stopped. Only on this laptop. Other wireless laptops working. Dell will connect using cable. It finds the router and signal perfect. Only will allow local access, so no internet connection. Read a post which said if AV subscription expired... suggested renewing AV and that would fix it. Did so. AVG. Didn't work. Have uninstalled McAfee. HAve done maximum power options. Laptop will connect to secure wireless however but not the one at home which is unsecure. Can anybody help two poor old geysers... Thanks!
