I have an arris g34 and it drops my internet for about 10 seconds every hour or so. I got a loaner arris dg3450 from my isp and it does not have this issue.
g34 intermittently drops net for 10 seconds but comes back

In this case we need to check the cable signal level to isolate the issue.
There are some important things that should be within a specific range in order for the internet to work properly.
First, the SNR should be above 33 on all of them. The downstream power should always be between -15 and +15. The closer to 0 the better connection. Finally, your upstream power should always be between +45 and +51
On all of those values you should not have more than 3 decibels (or dB) between the lowest and the highest
By having the values in less than that, your device will have interrupted connection, slow or no connection at all.
Please follow the steps mentioned on the below article to check the cable signal level.
