Hi,
I have not been able to connect to the internet via my LAN for about 1 week. The problem happened suddenly when I moved my laptop to another room and unplugged my ethernet cord; ever since then my connection says 'Local access only, unidentified network".

My connection is directly to the modem via ethernet cord, I don't have a router. I'm not sure what to try next, should I buy another nic? Any suggestions would be very helpful, thanks.
