I figured out what I was doing wrong!
I was trying to update it to the merlin firmware from work via the portal,
When I VPNed into my network and did the same thing from one of my machines on my LAN it worked !!
Hi all,
I hope someone can help,
Im new to customising the firmware on routers so I may be missing something simple,
I have a RT-AC87U with the latest Asus Firmware 3.0.0.4.382_50702, and im trying to put on the latest Merlin Custom firmware...
