Can I split a coax cable and use on output for TV and the other for my internet?

[aka1nas]

I was told I could do this with a standard splitter as the internet signal and Tv signal run on the same cable. But, I lost my cable connection when I tried. Is there some special hardware that I need for this? Like some kind of demultiplexer? I bought a splitter that had powerpass and I made sure to use some decent RG6 cabling.

I do it on mine, and I have yet to to have any speed problems

What kinda cable are you using? I assume you said it worked before...so is the cable you split the same as the cable going to your modem now?

A standard splitter oughta work (assuming a decent signal to start with).

If there's an amp in the line, make sure it is an amp with bidirectional signalling (like for digital cable / pay-per-view capable).

Maybe verify that it's a 900Mhz/1Gig/2gig splitter. Some of the older ones are for the older cable system, and only pass up to the 400-500MHZ range.

Maybe try another cable (store-bought is preferred to minimize the chance of a mistake / poor connection).

That's about it, it should work.

Good Luck

I just used some cheap cable and a splitter I found laying around, and it works perfectly. It depends on how strong you signal is if you wanna split your line with a cheap splitter/cable. If it's strong, cheap will be fine. But, if it's week - go out and buy some quality stuff

If you use a splitter for cable TV and cable modems, use a 1+GHz rated with a low db loss on the outputs. I would recommend a 2 way in your case since it will be less signal degradation, and you put your modem on the hot lead.

Just make sure the splitter is bi-directional, if it is and you lose the signal to your cable modem, you can get a bi-directional signal amp from radioshack for around $20-25 for a single output model (there is a 4 output model for $50).

You have to use a good splitter. Cable modems will only work if signal levels are within a certain range, and when you split the cable you'll mess with it. Try to get a good quality splitter and it should work.

 

[aka1nas]

weird enough, it works with the other side of the splitter. Maybe those cables weren't exactly identical quality?

You may have a 'Tap" not a spllitter. A tap peels off one leg, which is down about 9db (each 3db is half the signal...so half of half, then half of that), but the "through" port is only down a couple db.

Whatever.

FWIW

Works for me.

I have four TVs, five VCRs, my cable in for my ATI AIW 128 card AND my modem all connected to the same cable in one way shape or another and my internet speed is very fast.

it's actually called a directional coupler, and they come in varying values. a 9dB DC(directionl coupler) takes whatever you have coming in the input subtracts 9db and sends the remainder down the tap port. the thru port usually has a very low insertion loss, anywhere from 1.5 to .5dB.


aka1nas: how's your tv picture on the lower channels? snowy/grainy? how does the cable get to the modem? is their another splitter?

what kind of modem do you have? if it's a motorola/GI surfboard that'll help.... report back.. or PM me..



do not whatever you get anything from radio shack..... no amps, no splitters, no cable.... they make the crappiest sheet out their and it's horribly expensive....

you might be able to call the cable co, and get them to adjust the amount of signal sent to the modem from the outside giving you the ability to use a 2way/DC6 inside for the AIW.
