Actually not. Won't even look at them. But my RR modem will not work
through a 900 Mhz splitter and works flawlessly with the 1Ghz splitter that
is on it now. And yes, it makes a visible difference. Otherwise there
wouldn't be such an animal.

Screw monster cables. They're for yuppies kids.

Lowes has a good selection too. That's where I got my last digital spliter
when I was upgrading my dad's cable system.

Higher frequency splitters are easier to find now that they are used
for satellite.

My cable modem is a Motorola SB5120, which can provide information
about the connection. According to its status page, the downstream
(receive) channel is on 117MHz (channel 99) and the upstream channel
is on 35MHz (T-12?, below channel 2).

For one thing, the signal coming from the 3.5dB port is 3.5dB stronger
than that from the 7dB port, the numbers in question being the level of
attenuation relative to the input port. That increase in signal level
might have been just what was needed to improve the situation. Of course
it might have been just a bad connection and any disconnect-reconnect
might have fixed it just as well.
