Asus XT9 WAN question

[0ID]

I'm thinking about how to speed up the backhaul from 1G to 2.5G to 2 Ethernet connected XT9 mesh satellites.
In the manual I found an option to use LAN3 (1G) as a new WAN, then connect a 2.5G switch to the original 2.5G WAN port to which the backhauls of 2 nodes + a 1G link would go.
The manual describes how to set up a dual WAN, with one option being to set LAN3 as the primary WAN and USB as the secondary. I don't intend to connect anything to the USB port. Will this work? My internet plan is 1000/300.

Sure, it would work and you are more than welcome to try it (always good to try new things).

However, unless the cable used for the Ethernet backhaul is a tested CAT 5e or better you may experience connectivity issues. My AX86U Pro and AX86U have 2.5 GB ports and I have had problems maintaining a full bandwidth connection especially when I select the Ethernet backhaul mode. Often the node would go completely off line and with the WIFI backhaul disabled the node would loose connection.

And I ask: Why do you need a backhaul tha exceeds the WAN connection bandwidth? 1 GB is adequate for most home network use. Keep it simple...don't change things!

Thanks for your reply.
The cabling (cat5e) should be fine, as the 2.5G switch connecting the two nodes reports a 2.5G speed, as does the GUI, and another connection to a 1G switch reports as 1G.
What's wrong with wanting a higher backhaul speed?
I was just hoping for a simpler solution as enabling dual WAN with unknown consequence's.

If the use case is just traffic out to the internet, then having faster backhaul gains you nothing except a traffic jam at the slowest device in the pipeline. Of course that is what buffers are for to a limited extent. If the use case is communicating with a server on your internal LAN, then yes, having faster backhaul can make that feel "snappier" if the server can keep up (internal storage transfer speed is one issue). If the use case is editing video to and from network attached storage, then you want the fastest possible LAN including all switches and cabling as well as the storage..
