I wonder if I can tag this question onto this recent thread and get an answer without having to start a new tech thread?

I can't get the new wireless router to connect to my earthlink account via my dsl modem. It is all plugged in, but it won't make the connection. The Earthlink tech was NO HELP and rather smug (he did say they offer wireless for $10 a month--yeah sure, and after a year I keep paying for their service but I would have paid off my wireless equipment).

The other option, which I am strongly considering now, is simply running the wire through the coaxial wall outlet (nothing is hooked to it, the cable was put in "just in case") up into the attic and down into the other room to plug into the new computer. In my office where the DSL modem lives we put in a special plug that has the coax and the phone line in the same J box and coming out of a divided faceplate. The phone connection in the other room is funky and needs rewiring anyway. I would simply tie the old phone cord to whatever I want to pull through the wall from the attic and pull the wire back down to where it needs to go, maybe even another divided faceplate. But is a probably 30 to 40 foot chunk of cable (ethernet) going to be as good as or better or worse than the wireless network? Wired is a heckuva lot less expensive. If I decide to move the computer, I'd have to run more wire.

I can take back the wireless router and the wireless network adaptor and get a wired-router and some of the right phone cord, or will coaxial work? Any thoughts?
