I really Cablecom but I don't believe they operate in Zug. WWZ as someone suggested above offer similar services and packages, although they might be slightly more expensive.
I have a TV/Internet/Telephone combination package with WWZ and it seems to be fine.
Their site is only in German but Google Translate works a treat:

| Try Cablecom. They have some great internet + phone + TV plans at the moment. And they can send you correspondence in English | |
