You Can Easily Keep Your Home Network Running During A Power Outage — Here's How

A power outage need not sever a home internet connection, provided the router and modem are backed by a battery uninterruptible power supply (UPS) and the incoming line—fiber, cable or DSL—remains powered. Laptops and phones can run on their own batteries, but networking gear typically dies instantly without backup, interrupting work video calls and online gaming. The article recommends sizing a UPS to the router's and modem's combined load and run time, and notes that a UPS also protects equipment from surges when power returns. The key caveat is that backup power at the home cannot restore service if the provider's own network loses power, so users should check whether their ISP keeps neighborhood equipment running. The takeaway for households is a modest hardware purchase plus planning, with the next step being to measure actual router and modem power draw before choosing a UPS.
