This isnt written in stone. The power cycle allows the modem to refresh and allocate the ip to the router.

So its power down pc modem and router.
Power on modem wait till its settled
power on router wait till it settles
power on pc job done.

In theory you can add pcs to the router and they will just work but sometimes the router will need to be rebooted or a repair on the network adapter.
