Excellent work john9527!
Flashed it last week, to latest build and it has been running stable since. Only thing I've notice thats a bit annoying is the port forwarding. It kills the connection for a couple of minutes when applying changes. This was changed in Asus firmware. Have not checked out...
RT-N66U

Been too long since i lurked around on forums, kinda forgot how they work. Thought I might had to flash it in a spesific way with usb or something. But if the built in way works im gonna do it as fast as i get home from work.
Flashed a couple of old Dlink Routers back in the days, but if someone can point me to a guide on how to do the flash to get this firmware up and running.
