Internet connection keeps dropping randomly
I have an Arris Surfboard SB6183 which is connected directly to the wall coaxial cable. I also have a separate router, and they are both relatively new as in less than a year old (~8 months). It is definitely not the router because the modem lights are the ones turning off. I have had this problem multiple times, and I have had multiple technicians come to "fix" this specific issue more than 3 times over the past year. I wasn't losing connection for maybe 5 months since the last technician vist, but I started losing connection again this week.
On the modem, I should have 2 blue lights which shows that the upstream and downstream channels are bonded which means I am getting high-speed internet, and that is what I usually get when my internet doesn't mess up. However, today it has stopped showing the upstream blue light, and it now has a green light.
Here are the logs for the disconnections (https://pastebin.com/zXP1uPdy)
Here is the status of the channels and such for the modem but this status is when only the downstream channel has bonded but the upstream has not when it is supposed to have both channels bonded (https://pastebin.com/Emh6uWvW)
I will try to post a status of the channels when both are properly bonded and I have 2 blue lights, but right now, it is just the downstream channel that is displaying a blue light.
Please help me determine the root of the problem. My last resort is to call a technician because they always say the same script, and it always leads to the same temporary solutions. Help would be appreciated. Thank you.
