– in a known clean initial state.
Routers are really small computers. As such they have to do things like
manage memory and run programs – which can sometimes bog down, and even halt,
after a lot of use due to software design issues – most typically internal
memory management and memory fragmentation within the device. When that
happens, they stop functioning, or they function erratically. For example, some
websites work, others don’t. Maybe some are slow, or maybe everything
Routers are also electronic devices – and are sensitive to power surges,
