Bought new modem and upgraded to Gig - Only get 300Mb

I was previously on a 70Mb plan, and getting speeds around the 40's, but was having a lot of drops and upload was in the single Mb.

I upgraded my service to 1 Gb, bought a new ARRIS T25 modem and was able to get it activated. I never had to call anyone, it just seems to let me self activate on the website.

I'm now getting speeds in the 300's Mb at max. I tested both wired to my wifi router and wireless and its similar as long as I am close. My router support gigabit wired and 802.11ac wireless.

I have a suspicion that my outside coax is not the highest quality and could be impacting my speed. I tried viewing the signal noise numbers on my device status but I'm not sure. Can someone who knows more about this verify if I have a problem outside my device that I should have someone look at?

Just as a FWIW. Considering how high that your downstream power levels are, the upstream power may not be low. It may just be a very clean, low attenuation, and noise free return path / connection. It may be correct for your local system specs. There are spec variances between individual systems. YMMV.

4/5 of your upstream channels are a little on the low side.

When you test speeds test right from the modem and not the router like you posted
