This may or may not be a modem problem.

RF issues can definitely cause a modem to reset frequently.

What is your 'Power Level' under the Upstream section of the diagnostics?

Also, what is your Downstream Signal to Noise Ratio?

Your upstream TX power is lower ( which means less attenuation, better ), and your receive looks much better.

Across the board, it looks better.

Did you re-configure any wiring, or did you just straight swap modems?

Also, what plan do you have, 4000/512?

Do you have a router, maybe?

Your dl speeds look better, just not sure about the 1.5Mbps.

Here's mine from Cox, for example  - 4000/512

It does look like your router may be slowing you down a bit, or other traffic from another PC on the LAN.

As for the receive level, the temperature has a large effect on the levels.

My Rx is about 5dB higher at night; when the outside heats up during the day, it drops a few dB.

That is normal, I am running between -3 and -8dB Rx, with no issues.

Has your modem reset since you installed the new one?
