What modem/gateway do you have from cox?
What firmware is on them?
What are the led's on it doing?

Arris modems at both locations
Firmware versions are unknown as you can't login to the routers
Have to check the lights, however....
both RAX35 routers were working just fine until a few days ago then no worky no more.

Which arris modems?
When more than 1 device goes "bad" at the same time, its makes me suspicious of either a firmware update, a change in the setup, or something with the system. the odds of both of them going bad in such a short time are really high.
I'd take a look at the led's to see what they're actually doing. It could be a corrupt firmware or something.
That you can force new firmware back to them.
Or it could be a double nat issue as netgear routers don't play as nicely with double nats.
did you ever check to see if they've changed their default ip address? maybe if there's a double nat they're on the 10.0.0.1 address.

Again, key will be what your led's on it are doing (when you get the chance).
If they're on appropriately, then it usually isn't a corrupt firmware issue (not saying it isn't). But some setting issue we can work on.
If it is a corrupt firmware issue, then we can use tftp or nmrpflash to force firmware to them. I'll go over those methods if we need to do them.
So whenever you're home, Plug one of them in. Once its been powered on for a bit, make sure to factory reset it. Push and hold reset for 7-15 seconds while its powered on. the lights should blink/change when held long enough. Don't have it connected to the modem at that time.
