AX86U Pro - Testing with 2.5Gb WAN

[vic88]

Just testing my new AX86u Pro connected to ISP (Rogers) cable modem using the 2.5 Gb WAN port with a CAT6a cable. I get about 1800 Mb/s on the router's speed test (firmware 388.24199). From my desktop on the 1 Gb wired connection I get about 850-890 Gb/s using SpeedTest app.

In this configuration, I was curious if the regular 1 Gb WAN port could be used as a LAN port - sure enough it works. So with WAN connected via 2.5 Gb port, you have 5 1 Gb LAN ports.

Welcome.
Correct. If you use the RT-AX86U Pro's 2.5GB port as the WAN port, then the 1GB WAN port can be used as a 5th LAN port (5 x 1GB LAN ports). Conversely if you use the 1GB WAN port for WAN, then the 2.5GB port can be used as a LAN port, making 4 x 1GB and 1 x 2.5GB LAN ports.

Well if we do use the 1 gig as wan even tho we connect to 2.5 port as lan wouldn't it not output 2.5 because of using the 1 gig wan port?

May eventually exceed Gigabit with aggregate WAN + LAN traffic to whatever is connected to 2.5GbE port.

As indicated using WAN Aggregation with the 1GB port(s) could potentially yield up to 2GB for any 2.5GB LAN device connected to the router's 2.5GB port in LAN mode.

[WAN] How to enable WAN Aggregation on ASUS router? | Official Support | ASUS Global

WAN Aggregation combines two Gigabit networks to increase the bandwidth up to 2 Gigabits. When your ISP or LAN devices provide two network connection sources with LACP-IEEE 802.3ad (LAN Aggregation) support, you can use WAN Aggregation function in your ASUS router to get faster WAN transfer speed.

 

[Tech9]

I was actually talking about combined traffic WAN + LAN to 2.5GbE connected device without WAN Aggregation which requires 802.3ad support on the modem side. Something like Gigabit download from WAN + Gigabit file copy from another LAN port. In theory - possible. In reality - unlikely.
