Update: So nothing much has improved. Still getting same log entries, with random disconnects and it seems that ingress is still an issue.
Spoke to field supervisor who stated that put a "ping plotter" and didn't see any disconnects, not sure what exactly that does, sounds like it just monitors the modem being up. The issue obviously is not that the modem fully disconnects, it's that it's frequently switching profiles to avoid some sort of noise or something. These switches cause my service to intermittently drop which drops connections randomly on my works VPN as well as any gaming session I may be in when I do play. If profile switching had no end user effect, I really wouldn't care but unfortunately it does.
Supervisor stated that he's going to have to push this up to the CIT team or something?
I have a feeling this is one of those issues that may not be so easy to resolve just by the nature of the problem. It's an older community, lots of older houses, old lines, etc etc so just seems like a tough task without doing some overhaul of the lines or something? I don't know, I'm just shooting in the dark here.
Ping Plotter pings the modem, and if the modem goes down, even for a second, the ping is dropped. If there were no drops, it indicates you modem is up and online , both send and receive. Have you ever tried bypassing your router, and test with a computer connected direct to the modem and see if the results are different. You could be dealing with some kind of interference at the router?
I see. The tech said for most of the time it was fine besides one time thus the reference up to the CIT team. But my experience does not correlate to it being fine "most of the time" I lost connection several times and each time I would lose connection (VPN would log off or I'd get kicked out of Diablo IV), That's how I would know connection was lost. I would immediately log into the modem and sure enough, "US profile assignment change" entry was present just at that time of disconnect.
Would interference at the router cause modem to switch Up Stream profiles?
I had this issue when I had my RT-AC68U and CM1100. So I got a new router RT-AX86U Pro+CM1100, same issue. Then I got a new modem and tried the new modem with new and old router. Same random drops and messages in both CM1100 and S33 modem logs. I am pretty sure my equipment is not the problem here.
I'll have to figure out a way and disconnect the modem and plug it directly into a laptop and let it run over night to see. It's not practical for me to hardwire my desktop to the modem directly and use it for few days to see if the drops happen. If I'm still getting log entries of of US Profile assignment change with router disconnected then I can further confirm the issue is not on my end. Thanks for the suggestion.
When you lose connection, look at the modem. If the 4 lights, power/us/ds/online are ALL solid, that modem is online, and the issue may be elsewhere.
Also, probably don't need to do it for a few days, if it happens several times a day, then connected using the VPN, for several hours should be sufficient to give you an idea.
Also, when you connect a device directly, ensure your router is powered off, and you reboot the modem after connecting the computer directly.
