NETGEAR R6400: OpenWrt Compatibility Report

The NETGEAR R6400 runs OpenWrt from snapshot builds only on the bcm53xx/generic target, so there is no stable release for it yet. Its WiFi 5 (AC) wireless on the b43 driver rates limited for open-source driver support (0.35/1.0), installation is rated easy, and it is no longer sold new. Its wireless does not work correctly under OpenWrt, so it is listed here for reference rather than as a recommendation.
