We can attempt to push a firmware update to see if this will help, though V6.01.07 is approved by Cox. If issues arise after attempting a firmware push, then you may need to perform a factory reset to your Cable Modem. Do you have a signal amplifier attached to the coaxial cable or is there a splitter or barrel attached to the cable?
The modem is connected directly to the wall. I had a tech out here yesterday and he bypassed the amplifier coming into the house (recently canceled TV service and the amp was causing noise in the line) which seemed to fix the issue for about an hour. I called NETGEAR a few days ago and they said the firmware for Cox should be v3.01.04.
If I do a factory reset on the modem, will it update automatically when I reconnect it or do I have to get ahold of Cox to get it updated?
