For OpenWRT, if you'd like a Netgear R6300 do not get the v2. I've been told on OpenWRT's IRC just recently its not supported so you won't get usb, ethernet, wireless etc.,pretty much all that is vital. Whereas v1 is supported and said to have worked, it's not on the officially supported hardware list. There isn't much info on this model with regards to openwrt I'm afraid. In fact, I'm atm busy trying to build a custom fw for it myself & will update if I manage to get it working. (Though fyi, I can confirm DD-Wrt is working for this model)
