I've been having intermittent disconnects throughout the day for a good 3 months now. Switched out everything including getting a new modem, stopped using my external router, and changed the ethernet cable as well as the coaxial cable. I've called Rogers at least 15 times in the past two months and they keep saying they don't see any disconnects and anything wrong. I have no idea what to do right now about the situation and it's disgustingly annoying.
I have already two tickets open with them, and I did exactly the same you did. changed everything.
I think it's time to change ISP soon.
some additional information: had 2 technicians at my house, both reported noise on the line, both opened internal Rogers tickets for other teams to inspect/fix lines. Both these tickets were closed because when measurements were done they found signals good. I guess some Rogers employees do not understand the meaning of "intermittent disconnects" 🙂
after another call with Rogers support, i insisted on trying something and they agreed to replace my cable modem. They will send me a replacement, same CODA-4582U model. will update how it's working after switch
I am sorry, but it won't work and it won't change anything.
I did the same and got my replacement last week. Same issue
i got my replacement CODA-4582U installed (same model)
issue is NOT fixed, just got a 7 min outage starting at 11:36 AM EST
what's really interesting is that at outage time, on my work laptop i was having a Teams call (with Screen Sharing) and this continued uninterrupted. Cisco VPN client (in the background) disconnected and was trying to reconnect.
from my personal computer, i logged as cusadmin into cable modem web-interface and tried to ping Google DNS server 188.8.131.52. Result: 100% packet loss
But my Teams call continues uninterrupted, Teams chat was not working!!!
UDP traffic (used by Teams calls) is NOT impacted by these outages
ICMP (pings) and TCP traffic (including Teams chat) stops
will call Rogers support and see what's next
