If you look at Merlin's web site, you will not find the rt-n56u among his supported routers. The newer rt-ac56u is more widely supported.Just bought a n56u for use as a secondary router. Tried to flash the most recent Merlin build but it failed. Tried downloading a second copy but that failed too. Error message is about corrupted file or transmission error. Managed to flash Padawans build wo errors.
