My dad is having problems connecting to the internet on this computer. He has tried using a Wireless Adapter to no avail. The problem with the internet is that even though the NIC is connected, the browser won't go to any websites. So I decided to help, but when I clicked repair connection, it did not work and said TCP/IP Failed TO Query. This prompted me to go to the Services and try to start up the service. I went into the properties for that service and went to Dependencies and Windows Firewall was listed. Windows Firewall, when I started the service, failed to start. What could be the problem?
Check that your wireless device or Ethernet options are installed correctly. Not sure how but its possible that a driver is out of date and decided not to work with a modem/router, or internet connection update in the tcp/ip somewhere. I suspect this because it's an older unit.
