Power surge killing internet

There appears to be an issue with the cable line in my neighborhood. Every time there’s a storm, and it’s been daily lately, I get a text from Xfinity letting me know the cable is out. On top of that, I’ve lost two modems in the last week due to some kind of power surge. I don’t lose power and nothing else quits working, but the modem keeps getting fried. I think it’s the cable and not the power because the other item plugged into the same outlet is fine. It’s a two hour drive to the nearest Xfinity store and back. I can’t keep making the trip and something is obviously not right in the cable line.
