Arris Surfboard SB6183 Modem issues/dropping internet connections
Good morning/afternoon everyone,
I've been trying to figure out what's been going on with my internet the last couples of days. I have a TP-Link AC1750 router and I have done everything I could do on that end to rule them out to be the issue. So I looked through my modems event log, and this is what it showed me which makes me think it is the culprit behind my spontaneous internet dropping/reconnecting. I apologize for the long post ahead of time.
Here is my event log and status screen.
Thank you all ahead of time.
