I reset my Netgear WAC124 with stock firmware to factory defaults and would like to install OpenWRT. The problem is that I can't get past the login screen; without an Internet connection a message appears that first setup can't be done offline.
With an internet connection I'm stuck in a loop to login using my Netgear account followed by the router checking Internet connection after which I have to login using my Netgear account again, it's a nightmare!
That's why I wanted to flash OpenWRT using the TFTP method (which I successfully did with another Netgear router) but this part is missing in the wiki. Also the generic way did not work, the flashing process did not start.
The WAN connector is used if the device is in AP mode (not repeater mode) with the stock firmware. Not needed but I guess the pro is you get all the 4 LAN ports at the back to use
Yes and yes, because it seems it also has some sort of router functionality built-in. But since I wasn't able to play with the stock fw I can't tell for sure
