Fortunately, this didn't cost us a cent. The cable guy told us what the problem was and gave us a new cable that runs between the modem and the computer.....no charge for any of that. My hubby said we had a fairly new Ethernet card which he installed in our old computer at one time so he found it and installed it in this one and it worked!! (it stressed us out and took us about 2 hours to do the job)

Thanks for your reply Sky.
