I've switched my Internet service from Cox Cable to AT&T DSL and now want to extend my local ethernet from my upstairs office to the living room downstairs. Rather than running a new Cat5 cable outside the house, I see that the existing obsolete RG6 (75 ohm) Internet cable runs *exactly* where I need to go. Is there some kind of passive transformer that will let me run 10BaseT over this?
I know that years ago Thinnet Ethernet was run over RG58 (50 ohm) terminated by 10Base2 repeaters. I'm not sure it makes sense to go this route. Even if I could use RG6 for this application (will it work?), I think I'd rather run new outdoor Cat5 than buy a couple of these repeaters and pay for the electricity they use 24 hours a day for as long as I live in this house.
