Personal Modem and router on Cox not working

Did you call cox and get them to set the modem up? You can't just plug your modem in and have it work you call cox and give them some of the numbers on the modem and they allow it to access the internet.

I meant to say I had it provisioned and it still didn't work.

Did the modem reset when you had it provisioned? Are you Internet only or do you have TV as well?

Was your internet working before?

The first guy they sent was lazy. Proper procedure is to run DOCSIS checks at your wall outlet, any splitter or connection from there to the home run, at the ground block and at the tap (at the pole). That is all the technician can check, but he should fix any connections if the math doesn't add up properly at each point after he gets to the tap (at the pole...which should have been his first stop after speaking to you).

After that, it's the Network Technician's job to make sure the tap is working properly. That could have been the second guy. Who knows? According to the Broadband Residential Installation Standard, your connection shouldn't be higher than a 54 on the upstream and the input power at the modem should be between -8 dbmV and +10 dbmV ( 0 is the target).

If all of that checked out, it's the modem, and you need to get a replacement. Unfortunately, some modems do arrive DOA, as they can't link up properly. The modems the cable providers rent have the same problems as well, but it's an easy swap at that point.

Netgear makes pretty good modems and routers, but failures can happen with any piece of hardware that is made overseas. I've had good luck with the Motorola/Arris modems, yet I've seen Netgear stuff work great too.

I would take the modem back to get a replacement, but I would call Cox in order to see what kind of explanation or notes were placed on your account in regard to your current trouble if the last guy didn't inform you about what was going on. The probability of that having happened is slim, as people just don't do their jobs these days.
