Anyone know of any products with this capability

I am wondering if there is such a thing as a wireless cable modem
gateway that uses 802.11a and or g

I want the three in one box. Cable modem, Wireless Access point,
router.

I had read that net gear had something that was 802.11g but I did not
see the product available yet on their website.

I have seen the motorola product but that is just .11b and I wanted
either g or a.

Thanks,
