Ok, thanks everyone. That web page settings sounds very familiar to me, so that should not be a problem.
My set up is indeed wall socket - cable modem - router - PC.
The reason for me thinking that an IP address is needed is because this site that was giving me a tutorial said it was necessary.

Let me get on the Settings page and try to set it up there.
Thanks.
