Hi,
I have just got the router and I’m a little stuck with it.
I’ve tried connecting the ethernet to my router and tried WiFi but I just can’t get any internet.
The router is ar300m shadow
Which device is the “master” in your setup?
The secondary device needs to be connected by LAN, not WAN then.
Master LAN to Secondary WAN
I see that you’re connecting your AR300 WAN port to your LAN4/WAN port. Try changing this later one to LAN3.
