It is very random, but my panoramic modem/router will just drop internet connection. This started about 3 months after I started service with Cox. It may happen 5-10 times in a row, or not at all for days. It is very frustrating as I use my computer for work, I've contacted the cox office near me and they show that my modem will randomly disconnect, but they have no clue as to why. When I had my internet set up, the tech had to run all new wiring to my apartment, from the street so I know that the wiring isn't bad. The coax cable seems to be in good condition as well, with no obstructions in the connector.
I am having the exact same issue. I have had 2 techs out, and the last tech said he did everything that he could and that a maintenance team was needed. The maintenance team support ticket was submitted on Friday 11 Dec so I called on Cox support yesterday was on hold for 53 minutes to try and talk to supervisor about the status of the ticket. I got the standard "we are sorry for the inconvenience and are working the matter." Pretty frustrating when I drop out multiple times of every zoom meeting for 3-5 minutes. Definitely not getting the service I am paying for.
