The D6300 is essentially identical to the R6300 only this time NETGEAR have covered all bases with the inclusion of an ADSL2+ modem as well as the functionality to use any cable/fiber modem. The A6200 is NETGEAR's first USB Adapter to use the 802.11ac specification and enable users to connect to their ac equipment at above Wireless-N speeds.
