RT-AC86U and 5Gbit fiber

[spry107]

I have a Free.fr 5Gbit fiber router+modem that has 2.5G port and two 1G ports and 0.5G WiFi, offering total of 4.5Gbit over the wired network (at least in theory). As far as I've understood, AC86U does not offer 2.5G WAN port, and best I can get would be some sort of "dual WAN" connected to the same modem via 2.5G+1G or 1G+1G port, yet would it even be worth trying the setup? https://www.asus.com/us/Networking-IoT-Servers/WiFi-Routers/ASUS-WiFi-Routers/RT-AC86U/ mentions "up to 1.6G" of WAN-to-LAN yet I don't get it how they may claim that if single WAN is only 1G unless they declare that assuming dual WAN in load balancing mode?

I've read that AC86U has issues with dual WAN and manual routing is recommended, yet that's fine with me - I'd just dedicate one WAN to Google TV box (by wire) for streaming and use other WAN for everything that's on WiFi.

Ignore the 1600Mbps claims. It has a 1 gigabit ports. The AC86U would not be able to saturate a gigabit port even with a 4x4 client sitting next to it.

Understood! And over LAN? Would it be able to saturate two 1G ports in dual WAN mode if second WAN is completely dedicated to wired network?

You would need both the ISP router and the AC86U to support Link Aggregation. The AC86U doesn't seem to support it.
