Rick; Optonline is Comcast Cable's ISP here in Central Jersey. I am very satisfied with their service after switching over from AOL. Actually, you can still keep AOL as a dial backup as an option for something like $9.95 per month ... which I have not needed to do... or you can completely disconnect your dedicated phone line and save on the monthly charges to your local telephone company. With the cable hook-up, your on line all the time. No busy signals, no drop outs, and response is very very quick. I would never go back to AOL after experiencing the quickness and virtual trouble free cable service.... If you have a fairly new computer, you probably will not need the ethernet card... as most new computers already have that provision built in.
