Hello, I am hoping I can get some help with the setup I would like to have:

1 87R running latest Merlin firmware
TM AC 1900 with stock firmware

Due to living in an extremely rural area, I have LTE as my primary Internet provider.

I have 2 USB dongles, both of which work fine on each of the routers.

Since both routers only allow 1 USB WAN connection, I currently have to use them separately, with clients connecting on separate networks.

I would like to setup the 87 in a dual WAN in load balancing mode configuration and consolidate into 1 LAN.

I have tried turning off DHCP and NAT Acceleration on the 1900 and plugging an ethernet cable directly into the main WAN port on the 87,with no luck.

The secondary WAN connection on the 87 shows as no DHCP server.

I am fairly sure this should work, I just can't seem to configure the 1900 correctly.


Or, what about enabling both USB ports on one of the routers to each be a WAN connection, somehow?

Any suggestions?

TIA!

It depends what you mean by load balance. You of course can assign different machines to different routers. That is actually more easily done by the setting in the end devices using the default gateway.

Most other concepts of so called load balancing do not work well and you can not do what most people want the most. You can not combine the bandwidth to get one larger connection. The other problem with load balancing is you have to be very careful about sending even different streams of data over the different connections that come from the same machine. The common example is a game. Most game companies have some authentication server and then other servers that run the game. If you were to authenticate using 1...

Not sure what you are trying to accomplish but I suspect you need to be plugging the lan ports together. On the router with the DHCP disabled you would you would assign a ip like 192.168.1.2 assuming you main router is 192.168.1.1. You would then set machine you want to use the secondary one with a gateway of 192.168.1.2

The common example is a game. Most game companies have some authentication server and then other servers that run the game. If you were to authenticate using 1 connection and then try to run the game on the other you would be accessing from 2 different IP addresses. The game company will terminate the session assuming it is being hacked.

You technically can make a dual wan router work in this condition but you must tell it about all these conditions. Tends to be very tedious especially when you consider there are many sites that are made up of multiple servers. There is not magic way the router can know when even a person can not easily tell.

You end up assigning some machine to one connection and other machines to the other and it tends to be simpler to just do it in the end machines rather than mess around with load balancing configuration in the router.
