HardwareHeaven.com posted a review on the NETGEAR D6300 Wireless AC Modem Router and A6200 80211.ac USB Adapter

Wireless-AC is a reasonably new technology for home consumers, aimed at maximising speeds within our network and we looked at the R6300, NETGEAR's first ac capable product back in October finding it to be a very impressive product for those with cable/fibre connections. ADSL users were limited in their options though, needing to have a stand-alone modem to use it but now the D6300 Wireless Router is available, along with NETGEARs new A6200 USB Adapter. 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.
