</div>You might try a directional coupler instead of a hybrid splitter to feed the<br>
cable modem. My cable company does this exclusively, and will not use a<br>
hybrid splitter to feed a docsys modem.<br>
<br>
You also have to use a splitting device that is bi-directional, since a cable<br>
modem needs a two-way path, while TV sets etc. do not.<br>
<br>
Unless the powered splitter had a return path, even with little or no gain,<br>
I'm surprised the cable modem worked at all.<br>
<br>
Make sure any unused outputs are properly terminated, or you can get ringing<br>
or other problems similar to multi-path with antennas, these problems are<br>
more serious with digital signals.<br>
