RT-AX86U 2.5Gbps Port WAN Only?

[ChitlinNoodleSoup]

I've had people elsewhere tell me that the 2.5Gbps port on this router should work as a LAN port if not explicitly told to function as a WAN port. I have tried using it as a LAN port but connecting anything to this port causes the internet to go down and it requires a reboot to bring it back up.

Can anyone confirm this one way or the other? Thanks.

Yes, one of the first things I tried (to QNAP NAS with 25' Cat5e Ethernet cable), about 18 months ago.

Works fine for me. What firmware version are you using?

Did you have to do anything in the router settings to make this work?

Latest Merlin.

"Latest" isn't very helpful to people reading this thread.

2.5G LAN/WAN defaults to working LAN port5 here.

Also works as WAN port; default WAN/Internet then becomes LAN port5.

No, as @OzarkEdge alludes to also.

Other than making sure I did a full reset after flashing to RMerlin firmware and then not using a saved backup config file.

Good call. I flashed the firmware again, did a reset then reconfigured. I now have a 2.5Gbps LAN port to go along with my 2.5Gpbs NIC on my NUC. Not sure what good it does me but at least they match!

Even when you don't need the higher throughput, you benefit from lower latency.
