Setting Up Ethernet Network

[JonTSM]

I am extremely new to how Ethernet works and pretty much clueless about network setups.

So I want to setup an ethernet network in my new house which I've discovered to have CAT5e cable in every room's wall with telephone jacks. Each cable just runs to the boiler room in the basement where it's just sitting there, not connected to anything. We don't use a landline.

I want to convert each/most telephone jacks to an ethernet jack connect them to a networking switch in the basement, which then connects to a router in the living room. However I'd rather not drill a hole between floors.

Here lies my question, Can I use the ethernet jack that is right next to the router to go into the uplink port of the switch, which then connects to each bedroom's ethernet jack? Will this work?

As long as the router is on the same network as your devices, yep. They just have to be connected to the same network. Why not stick the router in the boiler room? Then you could put an access point somewhere else in the house if you need it using one of the ethernet jacks.
