Internet not connection?

Question

i can connect through wireless but for some reason when i use the wired connection it doesnt work. i tried the wire on another computer and it worked so its not the cable. what could be wrong it was working fine the other day?

Answer 1

Check you TCP/IP settings; open the command prompt check the ip address and default gateway; if all the settings are correct it may be NIC card issue.

Answer 2

could be your TCP/IP settings were changed on your ethernet card (not the wireless) or may even be disabled.  if you don't have the laptop plugged into an AC outlet most PCs will disable the internal NIC as well to save power.

Answer 3

start, contol panel, network connection, add new connection...follow the directions

Answer 4

go to Network Connections and check if you have Local Area Connection.
