You might also need a bi-directional amp, if your cable modem is after the amplifier. The modem needs to be able to send a signal back to the cable system.<br>

If it were me, I think I'd put a splitter before the amp and put the cable modem on one leg of the splitter. This is assuming the 3 dB loss of the splitter isn't too much for the modem, but it usually isn't.<br>
<br>
In general, when I had a cable modem, I tried to put it on the first split. e.g., if I had to go to three TVs, I'd use a two-way splitter with the modem on one leg, then put a three-way splitter on the other leg for the TVs. TVs are usually less picky about signal loss than modems.<div>
</div></blockquote><div><br>This is how I have it, but in addition to 3 TVs, that second leg is also going to my 4 mythtv tuners. My cable modem was on a leg marked 8db, while the TVs and myth were on the one marked 3db or something like that. Just for kicks I reversed the two, and so far I have no artifacts on any tuner, or TV. I must be right at the borderline of usable signal, and I guess the specs stamped on the splitters is a wild guess.<br>
<br>I'm seriously considering going all OTA soon, since the networks are pretty much all that's available in the clear, and the OTA signal is more reliable than comcast, despite being 40+ miles from broadcast using a coat hanger and tin foil DIY antenna.<br>
