I have an acer laptop travelMate 2480 running Windows Vista. I have attempted to access the Internet using local wifi connections.however when I log onto a wifi connection both secure and unsecured. The wireless network cannot diagnosis the connection problem. I eventually get a message that says "cannot communicate w/ DNS server (144.230.82.74). It further states windows found a problem that cannot be repaired automatically . I am not computer savvy and would appreciate any helpful input to resolve the issue.
