Hi everyone,

I have just had a new fiber connection installed and purchased an ASUS RT-AC66U dual band router.  The telecom provided modem/router was not coping with running my Sonos music system and I wanted to future proof the household with growing children beginning to run more and more devices.  I have no idea how to get the AC66 up and running. I presume I have to connect the WAN port directly to the optical network terminal (this is not covered in the setup instructions, nor could I find anything on the ASUS support pages).  After that I understand that settings have to be changed or provided, but have found that to be a nightmare.  I see from the fourms there has been discussion around this router before so I'm sorry if this is repetitive but I could not find any clear directions on how to get the AC66 up and running.  

Can any one help with an idiots guide to setting this router up please?

Thanks
