That's funny.. I'd swear that it's plain old twisted pair bell wire that runs about 6,500 feet from the remote DSLAM to my house. I wonder why I'm getting 2900/670 down/up. Must be that fancy CAT5 cable that runs between my computer and the modem that does it. (I always use an external modem) Reality is that you can push Gigabit down a two-strand barbed-wire fence if you have the bucks to spend on the equipment at the ends. > > If you had bothered to do some research you would know this. > > I recommmend you do some basic, prerequisite learning of > basic core technologies before trying to bite off more than > you can chew.

If you are trying to smarten up poor Radium, you'd better take your own advice.
