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.
Someone from CIT did call me this morning and informed me that there is some work going on in the neighborhood (always is apparently), there's also other properties on my street they identified as source of ingress which they padded in the past (whatever padded means) along with some split connectors they located across the street. They asked for a few days so I can wait and see.
I can't see the light as modem is not in my office. By the time I make it to the modem, internet is back up.
I will have to get a backup provider. I unfortunately am not able to completely take the modem offline as I'm not the only one who works from home or relies on the internet. I should have a backup ISP up soon and then I can switch everyone else over to that while I try and figure out what is going on with the COX stuff.
I will be honest that if the backup ISP ends up performing as well they claim it will (1gig up/down fiber), I might just call it quits with COX. There really is no benefit over other ISP, cost for COX is same and performance is less. The only reason I'm being stubborn is I've been with COX for 18 years and they've been overall good and reliable. WELL, I also didn't really have a choice before as DSL was out of the question and they could only provide about 25/5 connection. Now I do but still want to give COX benefit of the doubt.
Thanks for the tips, I'll try doing that this weekend.
Let us know!
