Solved Wired and Wireless Combo questions

Hi, I hope I don't make this too confusing.
So, in room A, I have the cable modem (with only one output LAN port). I also have my TV and a DVR in the same room, and want to hook them up to the internet.
In Room B, is where I have my router, that will give wireless to the rest of the house. I needed to move the router to that other room for total coverage.
1. Optimally, I would like to add a LAN switch right after the Cable modem and hook into the Room A items. Then another port I will send to my Router and thus make it wireless for the rest of the house.
Room A stuff does not need to be inside my home network (the wireless side), so not concerned about that. I have been reading and they said its not a good idea to put a switch between the modem and the router, as it might get confused.
Or I can insert the switch on the output of the router and just run LAN cables from the switch in room B to Room A tv and DVR. I don't want to use the electric outlet LAN adapters.

Which would be best? Like I said best is to insert the switch between the output of the modem and the input of the router. Everything is Gigabit.

Thanks in advance!

Curt

✔ Best Answer
Do not put the switch between the modem and the router.
Put the switch if necessary after the router and run the LAN back to the other room.
If the router has the ports you can just run the one line back to the other room and if necessary put the switch there to share the same line back to the router.
Your devices need to be assigned an internal IP address and this is done on the internal side of the router. Your TV, etc, cannot share your external IP address with the router (not even mentioning exposing anything to the internet directly without the firewall).

You have to be a little bit crazy to keep you from going insane.
