Dual wan aggregation

[Zakalwe]

I'm in a flat share with 3 people, each room has their own modem - if I asked one of the housemates if I could wire their modem into my routers port 4 and turned wan aggregation on, will I be getting 2x speeds? I have a 120tb unraid server and recently accidentally/not accidentally lost about 60tb of the media and half my shows are missing half the eps etc so I wanna make my downloads go+++

How Asus explains it.
[WAN] How to enable WAN Aggregation on ASUS router?

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.
....
Note1: Please note that the modem connected to your ASUS Router must support LACP-IEEE 802.3ad to make sure WAN Aggregation works. If you are not sure the front modem/router support LACP-IEEE 802.3ad or not, please contact your ISP.

Note2: WAN aggregation only support for Automatic IP and Static IP WAN connection type. If you are not sure the WAN connection type, please contact your ISP.

Note3: Please make sure the two WAN sources are from same ISP and same front modem/router.

The WAN aggregation supported by ASUS wireless routers vary by model, you may refer to the product user manual or the product specifications page to confirm if your router support WAN aggregation or not.

That explanation may be sprinkled with marketing speak and not reflect real world use. Make sure to read the Asus "Notes" on WAN Aggregation and what may be required on the ISP/modem side (LACP-IEEE 802.3ad) for the Asus router WAN Aggregation feature to work properly.

PS: Also understand that just because you may increase the WAN speed by enabling/using WAN aggregation, that doesn't mean your overall local network speeds will have a similar speed increase. Your local LAN will be limited to the LAN port speed capability of not only the router but the Ethernet wiring, WiFi connection, and client device network port capabilities.

It may help if you provided your router model and firmware version to provide additional context.

Be sure to check if the neighbor has download caps and what the charge is for overage.

There is no Dual WAN Aggregation.

Option 1, WAN Aggregation - 2x LAN links to 1x WAN (1x modem with 802.3ad support and 2x LAN ports)
Option 2, Dual WAN - 2x WAN links to 1 x LAN (2x modems to 2x ISPs with 1x LAN port each)

In both cases no single connection will exceed the individual link throughput.
