Only via RT-AC3200 can it establish a connection.
I possess an Asus RT-AX86U (zaku II ver) that is brand new, yet we struggle to establish internet access when connected directly via the network cable. However, when the older RT-AC3200 is plugged in, it successfully connects and the 86U can also find a link through the 3200. Our current network relies on an ISP line that reaches an ONT, which distributes power to an outlet we connect with an Ethernet cable. That cable then links straight into the 3200, resolving the issue. What might be missing here is something the 3200 setup doesn’t support in this configuration? Is there a feature removed from the older model that the newer one lacks? Asus support hasn’t provided clear guidance (have you altered the cable? Restarted the router? Have you changed anything else?). The local ISP technician is unable to assist via phone. A useful comparison chart is available at https://productz.com/en/asus-rt-ac3200-v...LZKw-B3pQ6. Any suggestions or recommendations for a compatible router are welcome.
Solution discovered: The problem likely stemmed from the DHCP lease provided by the fiber to the old router. Disconnecting the network cable from all devices overnight allowed the DHCP lease to reset, and reconnecting it in the morning resolved the issue.
Your ONT with a LAN DHCP server also acts as a fiber gateway, providing router capabilities. Placing another device with similar functions behind it can lead to IP conflicts and NAT complications. Simply plugging or unplugging the Ethernet cable offers only a temporary fix for a persistent issue. The correct approach is either enabling bridge mode on the ISP device so your router operates independently, or keeping the ISP in its default setup while running the wireless router in AP mode. In the first case, the ISP allows seamless LAN DHCP management, whereas in the second, the ISP still manages DHCP and the wireless router extends a wireless signal. Assigning a static LAN IP to the AP ensures network stability during IP lease renewals.
