My internet went down after a lightning storm. My cable modem is completely unresponsive and won't even power up, but everything else on the power strip is fine. So I am assuming the surge came through the coaxial. Someone suggested that the cable might fry any new modem I put on it, but that sounds off to me.Do I need to replace the coaxial, or will it be safe to just replace the modem?
I think just the modem needs to be replaced.
If you know the modem is bad, replace it. The coax should be fine, but even if its burned out- it will not harm anything. I have known only 1 person in my life named Ephrem. He would probably be in his 20's by now. Last name started with a B.
If modem won't power up, see if you can find an identical power brick and try that. What is important is the voltage is same and amperage is at or above what the correct one is. And the connector needs to be the same. If that doesn't work, replace modem.
No, it's not likely the coaxial cable, it's likely just the modem that went bad. In fact, the modem itself might be fine, you may just need to replace its power brick. Call up the modem's manufacturer and ask them if they can't send you a new power brick for it. It's not unusual that only one thing on a powerstrip went bad, it might have been the first thing in series on that power strip, and it took the brunt of the lightening strike, saving all of the rest of the items on that power strip.
