I recently purchased a new wireless router for home use; the ASUS RT-N66U. The router it replaced was a D=Link DIR-655. I have wanted a simultaneous dual-band router for several years, but until recently had not found one that worked as well as the single-band DIR-655. What finally pushed me over the edge on the ASUS was the need for ‘parental controls’ that included the ability to turn off Internet access for specific devices based on time. The ASUS RT-AC66U and the RT-N66U both had this feature. I decided to save $40 and go with the N version of the router since I do not own any AC devices.
The router makes use of a web interface for initial setup and making settings changes so there is no need for Windows. As an Ubuntu user I am always happy to see manufacturers that do not rely on special Windows only software for managing their devices. In this case there is one piece of software that is Windows only; the firmware recovery utility. Careful reading on the web indicates that the software does nothing more than setup a TFTP server for firmware recovery.
I am very pleased with the performance improvement of the router. I used Wifi Analyzer on my Nexus 7 to capture the signal strength comparison. For reference the green colored graph is the DIR-655 and the purple is the ASUS RT-N66U.
With previous attempts to replace the DIR-655 I had problems such as wireless dropouts and lockups. The worse of the bunch was the Buffalo WZR-HP-G450H, but the Linksys line also failed. I can report that I am currently very happy with the ASUS RT-N66U.
