Before the router starts working, does it synchronize with the network?

Question

Computer networks

Good afternoon, tell me, when we turn on the router, does it start working after it starts working in one cycle with the network, or what determines the characteristic of all (which I just saw in the store) routers at 2.4GHz?

Answer 1

No, it loads the OS, initializes devices, processes configuration files, launches peripherals, and only then "starts working".
If you are talking about frequency, then this is the WiFi standard, it has two frequency bands, which for simplicity are denoted by one number. 2.4 GHz is the more common band.
