WAN Link Aggregation RT-AC66U

[pmraiders]

Hi all!

I've been searching around the internet looking for a solution to my problem. I'd like to try and get 802.3ad link aggregation working on my router. I found this wonderful article on the wiki for the asuswrt project:

https://github.com/RMerl/asuswrt-merlin/wiki/Link-Aggregation

The problem is, this details configuring link aggregation for an attached local area device. I'd like to utilize the link aggregation feature of my Netgear CM1100 modem.

How would I set my modem up to link aggregate its WAN port (removing the use of one of the LAN ports to use it as the second WAN) to pull more than 1 gigabit out of my modem?

Edit: I have experience with linux administration, but not the asuswrt project or dealing with low level network configuration.

Thank you for your help!

This is not a question for the Asus AC Routers and Adaptors section.

You need to contact the supplier of the Netgear CM1100 modem instead.

Quite contrary, but thanks for trying to understand the issue. I don't need to contact netgear, I fully understand its capability. I simply need the link aggregation feature in that script to function as the wan connection for my asus router. Hence my post here. Is this not a good place to discuss asuswrt?

I am understanding to the best of my capabilities. Your question still asks how to set up your modem. Not how to set up an RMerlin powered Asus router.

Maybe you can clarify further for us?

Yes, gladly! My modem simply requires a single option to turn on its ability to link aggregate its wan port across its two gigabit ethernet ports.

I'd like to find out how to customize my router to connect to my modem and negotiate an 802.3ad link aggregated wan connection to my modem.

I haven't seen any documentation that supports this, just enabling link aggregation to attached local area available NAS devices or managed switches. This is achieved by apparently utilizing lan port 3 and 4 to create a single link aggregated connection. I'd ideally like to use one WAN port and one lan port to achieve this, or two lan ports, with that link aggregated connection designated as the router's wan connection, then re-purpose the WAN port as a lan port.

I hope this makes sense.

Thank you. I think I got it now.

Afaik, that is not possible with an Asus router though. The GUI options available are Fail Over and Load Balance in Dual WAN mode. But it will not aggregate the two ports with a single ISP.

Even if this was possible, the RT-AC66U you are using would be a poor choice as it is based on much older hardware. What are your supplied ISP speeds that you need to aggregate 2x GbE ports for?

WAN aggregation has recently been added to the RT-AX88U, see here. I doubt that it's even possible on the RT-AC66U because of the hardware limitations.

Now, that was my worry, but since link aggregation is possible for a LAN connection, wouldn't the limitation be in software for the WAN connection?

I did figure I'd have to upgrade anyways. With my faster internet available now and my more demanding local streaming needs its probably not a bad idea to get a router with a more capable backplane anyways.

The only reason I can think of to use link aggregation would be to achieve download speeds in excess of 1Gbps. I would assume that trying to make the RT-AC66U do WAN link aggregation would require disabling hardware acceleration, which would limit the router's throughput to about 150Mbps, making the whole process pointless.
