A customer has a laptop that is running Windows Vista. The computer appears to connect to the Verizon FiOS (Actiontec) router, but does not connect to the Internet. On investigation, I found that the computer can't connect to anything on the network. I cannot ping the router from that laptop, and the connection test from the router also fails.
I connected another laptop without a problem. I took the failing laptop to another location and was able to connect without any problem.
I have run SFC on the laptop, reset the router, removed and re-established the connection, turned off the firewall, uninstalled and redetected the wireless adapter, and uninstalled the HP Wireless Assistant. Nothing as helped.
What do I have to do to connect this laptop to the Internet through this router?
