Turning off Modem and Router

Let model sync first.
Let router dial in.
Let clients obtain their dhcp and whatnot.

I leave my router and modem on 24/7 but turn off the CRT monitor and computer at the end of the day. The modem, router, monitor, and computer are all plugged into a UPS. If I have to restart the router or modem I turn off the switch on the UPS instead of unplugging the brick. Everything seems to sync in okay.

 

Then you are lucky.

If the router happens to stabilize first, it may not pick up the IP from the modem that has not yet established a sync with the ISP.

And while it is not likely the computer will boot before the router, the same thing could happen if the router boot was delayed (perhaps while waiting for an IP from the modem).

I see no harm being caused by turning them all on at once (I assume through a power strip switch like that in dogbite's image) but it is just not SOP for booting a network.

 

My ISP used to need to register the MAC address of the device connected to the modem, which it would not do until the modem itself had established a connection with the ISP.

 

Was that many years ago? Before home routers were common? I remember when I first got my broadband cable connection (over 20 years ago), we were only allowed to connect a single computer to the Internet. Most households could not afford more than one computer. If you wanted to connect two computers, you had to lease two IP addresses, and they were assigned to the MAC address of each computer's NIC. But then home routers, Ethernet hubs and switches become affordable and commonplace, and the prices of computers came down and now ISPs don't care how many devices are connected. They only care how much bandwidth you are using.
