I'm following this because I'm having the same issue!! But in my case my old modem works better than the modem I got for gigabit connection. I have yet to see speeds over 200.

Is the "Online" indicator light lit steadily ?

Light is steady. Guy in the condo across from me has the same equipment and his download speed at the same time was 900+

You should read this post. Not regarding the modem but regarding the router. I might look into this.
