For about two weeks I have been unable to connect my wireless Lenovo laptop to the Internet. The computer recognizes the three major wireless systems I use and will connect to two of them, but it will not make the conection to the Internet beyond the LAN. At home, it won't even connect to the system. It recognizes the system but won't make the connection, even though the router is working fine. I took the laptop to tech support at one institution, and they ran some tests, even connecting to a line to see what was happening. They were unable to resolve the problem, though they did say it appared that the computer won't recognize the IP address, and gets an error message 169(I think). Does anyone know what I might be able to do? The computer is pretty much worthless without this ability, which it had and which was working just fine till suddenly . . . Thanks!!
