TP link have wireless 'client routers' for wifi ISP's (they call it WISP)
they work even better and simpler than the bridging - you log into it once, run the setup wizard which finds your wifi, you type in the password and bam - it acts like you're connected over wired (IP straight from the primary router), and you can run a switch for multiple devices, with the wifi speed being the only limit.
benefit is detachable aerial and you can move it around a lot easier, i used to do it to share wifi with a neighbour.
