Hello - First time post here. I've been hunting around to see if it's possible for the ASUS RT-AC3100 to have WISP (wireless ISP) mode enabled? ASUS firmware does not support or allow this but wondering if other firmware might? I'm discovering some manufactures/brands have different names for WISP e.g. client AP, wireless bridge, etc. I've always known the feature as WISP. What I'm trying to accomplish is connect my WAN via wifi client connection, have my router still serve as DHCP server, and firewall the downstream LAN. The RT-AC3100 I already have checks off a lot of boxes for other features I need so I am hoping a non-standard firmware turns this feature on. Thanks a ton for any help or input here.
