Why do you need to reboot the router?

Question

WiFi

When the Internet slows down, usually everyone restarts the router, but how it helps, speeds up the fallen Internet, I don’t understand

Answer 1

1. The processor failed due to a random failure: due to a power failure, or due to a cosmic particle. This happens in a black way in spacecraft - you just can’t reboot the processor when it is thousands of kilometers away from you. When under the table is another matter.
2. An error in the program, fraught with a crash or memory leak (in the first case, the program stops, in the second, memory consumption increases until it eats up all available memory). If the device is without an operating system, a program failure leads to a complete shutdown of the device, if with an OS, to a stop or restart of some process, which is fraught with a complete or partial loss of functionality.
3. Memory fragmentation with large uptime. Usually happens with constant chaotic selection-release.
Specifically, in the router - in 90% of cases, the matter is in the 2nd reason (less often in the 1st or 3rd).

Answer 2

Well, it depends where and how... At my work, for some purposes, there are cabinets with 11 years of uptime, they wrap a very important and critical function. When "the Internet starts to slow down", we think where to switch something

Answer 3

Well, suppose not everyone :) I, for example, do not overload :)
In cheap routers, memory "leaks" - errors accumulate in the process of work, which lead to the fact that the available memory becomes less and less, then it ends and the router can hang trite - TP -Link, for example, very often does this :)
