Thank you to those of you who are so generous with your time and are trying to help me.
Thought i would share what the computer said when it was hooked up to the ethernet cable on the boat:
Internet Exp can not display the webpage
-Cannot communicate with primary DNS server
-network diagnostics pinged the remote
but did not receive a response
Network and Sharing Centre
IPV4 connectivity local
Media State enabled
Speed 100 mbps
Bytes...lots sent...few received
LA connection properties-all boxes ticked
Client for Microsoft Network properties
I don't know if all this makes sense to anyone but i am at a loss and unfortunately now we aren't on the boat to try anything else with the system. We will re returning in Dec and had hoped it was a computer problem and it could be fixed by then...???
Thanks again for trying?!?
