Have see people with good tv signal and poor internet cable values.
Internet drop outs/failures users also had poot tv.
If no problems with internet, then I would check tv path.
> I know this is the same band. My modem says 3dB. Is that low?
Hmmm, mine i -1dbv.
> Can it tolerate a bump up to improve the TV signal?
Look up the specs on your cable modem.
I would not recommend you placing an amp in front of your cable modem.

Does your cable modem list the downstream and upstream frequencies?
Most commonly, downstream will be very high, like in the 600-700's. That
is well into the UHF channels (or cable channels 85+). Channels 2-6 are
roughly 50-88MHz. Upstream usually uses frequences below 50.
+3db is good. The recommendation is +15 to -15, although some
recommend trying to keep it +8 to -8. You also need to check SNR (Signal
to Noise Ratio). It should be 30+. Upstream should be below 55db.

Noise and problems with channels 2-6 often mean a poor cable ground
someplace. Double-check all your connections. Also, verify that any
splitters are rated 5-900 or 5-1000. Replace any that are unrated, or
start at 40 or 50MHz.
