Upstream Bonded Channels Power Level Too Low, How to Fix

I've recently bought the package with Xfinity that should provide ~300 Mbps download speed, however after setting up the network I found that my connections speed when tested was from 1-10 Mbps download at the most, not even to mention the upload speed which was consistently below 2 Mbps. This is incredibly slow and definitely not what I was paying for, especially when having faster speed is more important now more than ever with remote work. I called both Xfinity and my Modem company (Arris, My model for the modem is SBG6700-AC, which I was told should be able to support the speeds I had paid for) multiple times to try to fix the issue. I've spent more than 3 hours on the phone collectively on this. Arris says the issue is that my Upstream Bonded Channels Power Level is too low, below 45 dBmV (Mine are around 41-43 for the 4 channels I have). I checked all the other levels and they seem to be normal based on what the Arris representative told me.

 

What should I do? I called Xfinity to ask them to increase the signal power level but they said that they have set me up with a technician half a week from now when in reality I need this wifi signal as soon as possible. I'm also fairly skeptical that the technician will be able to fix the issue.

I'm not sure if the photo is popping up I believe an admin has to approve it first.

Per
https://www.xfinity.com/support/devices/#details
That device only covers up to 280. When you add a modem that isn’t compatible with your package, it defaults to a lower speed. Use the link to find something compatible. Also, your upstream levels are fine, Arris reps don’t know what they’re talking about
