Best internet service in Switzerland with which I can use my Asus RT-N66U router?

As the long title suggests does anyone here live in Switzerland who can advise me on which internet service I should purchase that allows me to use my wireless router.

I would prefer to use it as it allows me ability to run a wireless printer and backup storage also wirelessly as well as great wi fi signal strength and security.

I see alot of Swisscom all in one built in boxes. I was hoping there is a choice..

Thanks!
