i am trying to install a cable modem in my bedroom, but the signal is very weak. when i plug in the modem, directly to the cable jack, the cable ready light turns solid, and is good to go. however, since it is the only cable line in the room, i split it, so i could also have TV. this apparently made the signal to weak for them modem, because it wouldnt work anymore, and i might add the cable quality is quite poor on the TV. i followed the run that goes to my room and noticed that the singal has been twice split, priot to my splitting, so its actually 3 splits. as it stands, i cannot remove the splitters, because there are other television sets dependent on them. by the way, i tested the splitter i am using in my room with the modem on the original cable run coming from outside, and it worked fine. i also tried a different spliter, no more luck than before. so, i am considering buying an amplifier. i picked up a 10db amplifier from the hardware store, but it seems like crap. i am learning now that its only one way.... so the modem can't talk back to the cable co through it... plus, the cable quality on the TV didn't seem to improve. so i have a few questions, perhaps some of you can help! 1. who makes the best 2-way amplifier? 2. where does the amplifier go? before splitters, or after them? 3. what kind of dB's should i be looking for to see a noticable difference? thanks! bill

I dont know much about this, but I think the amplifier should go before the split. I just got an amplifier for free to air TV and it is 38dB so 10dB sounds a bit low. Look for something over 20dB.

yes the amplifier should go before the split, putting it after just amplifies an already corrupted signal. Note that amplifiers are intended more so for cable-tv signals rather than modem-signals and your not likely to see much, if any, of an increase in strength, could evenhurtthe signal further hmmm this sound more like a line issue than anything else. Check your lower channels like 3,6,10,29 and see what they look like. Are they clear or blurry? Whos your cable provider? You could also have a bad splitter, dont buy a radio-shack splitter for things like cable-modems, not reccomended. You want to try to have a dedicated line for your cable-modem if possible, if not than 1 2-way splitter at the source of where the cable comes in to the house is acceptable, than split the other tv's in the home off one split, using additional splitters if needed,andrun the modem line off the second output of the source splitter.

i have time warner cable. like i said, the direct run has been split many times, and it would be virtually impossible to alter the set-up. here's the breakdown. line from outside, at the power box i can see is split into a 2-way splitter. one feeds the downstairs, the other the upstairs. upstairs, there is a 3 way splitter, splitting that signal to 3 bedrooms. one of those splits is for my room, which the modem has, and does run off of. however, since introducting yet another split, so i can watch TV in this room, the modem stopped working! anyways, i am looking at ads for amplifiers on different websites, they seem to say it supports cable modems, and digital cable boxes. i know the one i bought doesn't, as it is only a one way amp. may i also add, that i noticied the box for this amp says, VFH/UFH/FM amplifier... well i know cable isn't VFH, or UHF, so is FM cable? i always thought cable was CATV. is FM isn't cable, would that explain why the 10dB seemed to do nothing to the picture quality? anywho, given my situation as it has been explained in further detail, is there anyway i can get this modem to work without having to get rid of the TV, or find it a direct run? thanks!

and i've tried a multitude of splitters by the way, all of which in cases where there was less prior splitting have worked with this modem. but, if you'd like to know, its a "High Performance Splitter"....oooo, i bought it at home depot, its 5-1000mhz.

You dont have to get rid of the tv, all you need to do is split the wire coming into the house. turn you tv on and start disconnecting cables from the 3 way splitter till the tv goes fuzzy and mark that cable, then do the same for the 2 way splitter. Basically you have to find the cable run that leads to your room. When you do find it youllhave to somehow make that dedicated. You can cut the wire and put new connectors on it, but id say if your havingthis much trouble, call your cable provider and have them comeout and run the wire. Heres what you need: I I Into house I 2 way splitter I I I I modem line 3-4 way splitter I I I All tv's in house 2 way splitter I I I I TV Modem

well the way it is set-up its impossible for me to make a dedicated modem line... here's a diagram i made on paint of my setup to make it easier to understand. http://www.geocities.com/wrmiro/diagram.JPG in the event that shows up as a link, just copy and paste that address, or it won't work.
