Why do I need to reboot electronics?

Your router is the same: every reason rebooting a computer can solve problems applies. Just like on your computer, you’re not actually solving whatever is causing the router to crash, but you are allowing it to run properly again.

Sure, this doesn’t fix systematic problems, but it generally solves things in the short term.

Your Router Is a Computer
You might not think of it this way, but your router is a computer. Inside that plastic box is a CPU, memory, and local storage, all running an operating system. And like a computer, things can go wrong from time to time. Maybe a bug is causing a memory leak, maybe the CPU is overheating, or maybe a full blown kernel panic has taken down the entire system.

What’s the simplest fix for these sorts of computer problems? Turning it on and off again.
