I just purchased a used Gateway notebook model MX 7118. I'm having problems setting up an eithenet connection thru my cable TV provider. My desktop works great on this connection. On the notebook, I went to Start/Run and typed in (ping 127.0.0.1) and that test passed. Next I typed (ping google.com) and that failed. What should I do next? Assuming I may need a NIC how do I find out what type NIC I have and the part number? Last question is how do I remove the NIC from the notebook? I can't find a tear down manual. My serial # is N326161041342.
