Hello!
I wanted to create this post to see if I can get an answer, as google seems to give mixed results. This winter, I was thinking of getting a small generator incase our power goes out. We live in a rural area, so I have propane for heat, but was more worried about keeping devices charged and some lights.
I was curious if we had a power outage, if I powered my modem- would I still be able to have internet access? We have Xfinity but I wasn’t sure if there is a total power outage, if the internet would go down either until the local system is brought back up or if it had batteries/self generators so the network stays up during an outage.
I live in a rural area. A good size UPS will run your modem for a LONG time, and is automatic. I routinely work through power outages as a result.
However, being cable, if a tree takes down a power line - chances are pretty good it can take down the cable line as well. And that happens frequent enough that I also have Starlink as a backup.
So in your case it’s probably a big, “It depends?”
