Asus RT-N66

Devices with Broadcom WiFi chipsets have limited OpenWrt supportability (due to limited FLOSS driver availability for Broadcom chips). Consider this when chosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported. See Broadcom WiFi for details.

Supported Versions

Version/Model Launch Date Model Specific Notes
B1 2013 commonalities with the Netgear WNDR4500
B2 2014 HW same as B1, different CFE version

The RT-N66U and RT-N66W are the same except U has a black case and W has a white case.

The RT-N66R is the same as the RT-N66U. It is simply a repackage for retail sale.

Please notice that due to Broadcom BCM47xx driver limitations wireless support is sketchy.

In Chaos Calmer r45879, 5 GHz is disabled and 2.4 GHz is very weak (see: https://dev.openwrt.org/ticket/10852#comment:49)
