I replaced an Asus RT-N66 operating in AP mode connected to an EdgeRouter 4 used to replace AT&T's buggy normally imposed fiber routers via wpa_supplicant on the EdgeRouter. I wanted and bought the GT-AXE16000 for its much improved wireless and its 3 multigig ports. If I set the AXE16000 in AP mode, most of my wireless clients, although able to ping by name and IP, cannot connect to the Internet over this connection. All wired devices connected to the switch of the GT-AXE16000 can connect to the Internet without issue. All devices, wireless and wired can see everything internal to the network. I cannot figure out why the RT-N66 AP works but not the GT-AXE16000 set up in exactly the same manner. I've tried updating firmware, Merlin and Asus tech support to no avail. I'm pretty close to returning it since something seems to be amiss with the AP implementation but was wondering if anyone else encountered this and was able to fix it. Thanks!
