Cox modem fried by coax?
On modem #3 in the past 3 months... First modem displayed no lights. No internet. Tried the usual troubleshooting, turning it off and on, etc. Replaced modem, did not fix problem. No lights coming on, no internet. Tech came out and replaced the modem again, but this time plugged into a different coax outlet inside. Was out there several hours and now it works. A few weeks later, here we are with the same issue, no lights displayed on the modem. The power supply is a steady 12VDC, plugged into a surge protector. The circuit is not overloaded. I found there is AC voltage coming from the coax outlet inside, about 40-70VAC. I went outside to check the ground on the coax, indeed the ground is working. I'm assuming there is voltage leaking into the coax from the shielding being damaged, and it being next to house electrical underground. Help.
