When they first installed @home here, they had to run a separate cable from the box to my room because the existing cable had to much noise in it.

Maybe that's what's up with your non-working cable, got old and rusty.

maybe, but they just installed cable in my home 5 months ago so the line is new...ahhh im going nuts!

odd, i used to have cable and i wanted to lan up to play with a friend at my house and also play online, however i didn't have a router. being that he also had the same cable modem/service i did, i unplugged the tv in my room and screwed the coax cable into his cable modem and bam, he ran just as fast as i did. my only concern was if we were running off the same ip, when he checked his ip, it was still the static ip assigned to him at his house, but he never refreshed it, so i'm not too sure. i assume that your other 2 lines aren't properly upgraded to support the cable modem transfer.

When they hooked up my cable modem, they had to "activate" line I was using and the one I planned to move the Cable modem to. I wasn't sure if it was a load of crap or not.

When Cox installed @Home at my house, they had to take a filter off the cable line at the green box a couple of houses away. Then he had to place filters onto the splitter in the box on the side of my house. He put them on all of the outputs of the splitter except one (the one going to my room). Then he put a filter on the splitter that is in the wall that splits the cable into my room and my living room. Only that one jack will work because of the filter that they put on. The filter does not allow two-way traffic because it could damage televisions over time, or so they say.

damnit that sux!!

the cable modem used to work on that broken line...well it worked for like 30 min then it died completely....im not sure if i should call my cable company since they would have to re-activate that line and then it would be alot of hassle and i might lose cable completely...god damnit!!

Cable modems rely on signal strength big time. If you have to many splitters on the main line. Say you split into the house(apt) then split from there to the 2-3 tvs in the house each splitter cuts the signal down a bit. At a certain point the connection will become erratic.

Also, signal 'boosters' will fluck up a cable modems ability to get a signal. Make sure you don't have any of these in the house.

Try this....split your cable signal into two sets. One "set" should be just one wire going straight to your modem. The other set should be for all your TV's. If you need an amplifier, then use one for the TV's but you shouldn't use one on the cable modem coax. I have mine split like this, with an amplifier on the TV side with no problems. I have 7 or 8 jacks hooked up through the amplifier and one jack for my cable modem not amplified.

thanks for all your help

i think grey is right...the jack that is broken is probably a line that is split in my house...and the download rate is like 300kb slower than the the other jack...

i think im going to use the one that is not broken but i'd have to buy a longer cable wire and the walk way will look odd with a bunch of wiring...

i guess that is the price u pay for fast internet connection plus $30 a month!!
