For the last six months, I have had a horrible intermittent problem with my Cox cable network connection. Every day, between 5 and 30 times, the connection will freeze for about 1 to 2 minutes.
When this happens, I can get to all my boxes in my home network, I can get to the firewall/router, I can get to the cable modem, but I can't get past the cable modem. The internal web server on the cable modem says that the connection is "Not Operational".
I have phoned Cox Business repeatedly about this, and they tweak something, and it seems to go away for a while, or they look for a while and run their tests but can't see anything. I have replaced all my network cables. I have replaced the switches. I have replaced the firewall/router. I have even replaced the cable modem. None of this had any effect.
I set up a ping to my work site, and it would ping once every two minutes and log the result. This allowed me to work out how often it happened, and if there were any patterns. It happened a lot, and there were no patterns.
Last Sunday, it really went bad and we had several hours where the connection was up and down repeatedly. I phoned Cox Business and they decided there was a problem and they organised a tech to come and check it out. I wrote a complete record of the problems, showing what it was and what I had already done to try and eliminate it (replace my whole network effectively), and left it with Anne to give to the tech.
He arrived early Monday, Anne showed him my document and he read it and went out and checked the green box in the backyard, and the connections to the house. They all checked out good. He came inside and helped Anne move furniture until he could see the cable connectors in the wall. He tested them and he had an "Aha" moment. Those connectors were the original ones in the house, and they were at least 20 years old, and they had deteriorated. He said they were the problem and he replaced them all, tested it again and declared success.
I left my ping test up, and now after a week and a half without a single outage, freeze, dropout, or any problem at all, I agree with him and declare success.
My cable freezing days are over, we have a stable network connection again, and the mail and web server are permanently up again. I am happy again.
