I'm reading https://www.asus.com/Networking/DSLN12E/ and don't see any feature that can do what you asked. Looks like the wrong gear to me.
I prefer routers as a WAP (see google) and this powerline WiFi setup.
I'm not a networking specialist, but I bought a Asus DSL-N12E to be used to extend my home wifi. The guy in the shop recommended me the Asus, but now I have tried to find a manual or tutorial on the net to set it up as a repeater, unfortunately can't find any. I'm lost! Can anyone help please?
