Can I install new modem through router & switches?

I know the self-install instructions say to plug a computer directly into the new modem's Ethernet port to do the online setup.


My question is: will online setup work in my "real" configuration, where my PC is wired to the router via a couple of switches, and the router is wired to the modem?


Or is it truly necessary to setup via direct connection from PC to modem?

They tell you that to eliminate the possibility of issues with your equipment. You can self-install with your real-world setup if it's your preference.
