Arris SB8200 Dropping Out on Large Upload - Firmware Issue or How to Diagnose?
I have an issue where when doing larger upload (presenting my screen and cam video) that within 10-20 minutes I'll lose my entire internet connection. It only seems to happen on those type of upload situations and haven't had the issue happen when doing large downloads.
I updated my router firmware but also wanted to figure out how to diagnose if it's perhaps an issue with my modem or Cox service provider. I have accessed the ARRIS modem page and see Hardware version of 6 and Software version of AB01.02.053.05_051921_193.0A.NSH. But I have no idea if that's good or bad. That date may be May of 2021? Reading online it seems that I should not be updating firmware, rather Cox should. But Cox online tech support was bad, I mean really bad, they had no idea what I was asking about what version they are pushing to my modem (she was trying to sell me a different modem).
I'd like to understand what I can look for in event log in modem to determine if this is a modem issue or what.
And if anyone knows the right questions to ask or number to call for lower level tech support from Cox who can answer these types of questions.
