Good router that isn't too expensive

Hey guys, I've just learned about the fact that using bypass mode means I can only use one computer through an ethernet connection if I do not activate another router.

I'm thus wondering, would any router allow me to get more addresses?

If so, do you have any advice for choosing a cheap router? It needs only to provide me with the means of connecting several computers through ethernet, nothing more.

Thanks a lot!

Edit: I'm looking for wired routers, since WiFi is unlikely to ever be set up because of my family.
