I have just flashed DD-WRT on to my RT-AC66U router. The firmware build is still in development for this router, however, the build that I installed appears stable (build V24SP2-21286 by BrainSlayer). I have enabled wireless access to the router and can access it via my computer on both 2.4G and 5G. However, I can't get either my Blackberry or Samsung Galaxy S3 to connect. They both come up with authentication errors. I am using WPA AES as the encryption method.
