I have a customer with a laptop running Windows 7 Home that has lost the wired connection to the internet. When we connect wirelessly to a neighboring office wifi router it works fine. Also I cannot ping the wired router or other wired LAN workstations. The other workstations connect to the internet fine and can ping and access the problem laptop just not the other way. The laptop can see other shared folders on other workstations but not the internet or router. I have turned off the firewalls on the PC's but this didn't help. Also the network location for the wired network in 'Network and Sharing Center' is stuck on 'public' and I can't change it to 'work' or 'home'. The network connection name in the is 'unidentified network' and I can't change it. When I take the laptop to a different site and connect to a wired network it allows me to configured it as 'work' or 'home' and the internet works fine.
Is this an issue of the network configuration being saved in the router or ?????
It is a older Linksys router. Any info would be appreciated. I have to go back to the customer's site and right now I am stuck. Thank you
