We can defiantly suggest it, however this would be outside the scope of a Home product.  So you know we do have Business class multi-wan router specifically desgined for this setup.

I humbly disagree! (about home vs business)

Many modern homeowners want the peace of mind of high availability internet.  

I do not have a home based business but if I did, it would be even more critical.

I view this as an emerging and underserved market.

I am aware of the TP link products you inferred (TL-R470T+/480T+, etc) — if I were to go that route, I would have to use the C4000 as a downline AP and would also lose the main benefits of TP-Link Homecare (antivirus/quarantine, QoS, Access/Parental Controls, etc).

In the end, the ability to fail over to a backup ISP and restrict high-bandwidth services (Netflix, etc) is likely to be one of the next big premium router features in the (near) future.

There are a few reasons why I say its out of the products scope.   For starters WAN aggregation isn't truly two seperate WAN ports.  Its two phyiscal ports mad into a single logical WAN port.  In fact in some of our newer models we have stepped away from this and just gave the product a 2.5Gbps WAN port, so a customer doesn't have to give up a valuable switchport just to ensure they get the speed they are paying for.  

Also consider this.  There are very few homeowners who would be willing to pay for two seperate ISPs just to have fail over or even load balancing capabliities.  This would also require a signficant change to the software the home router runs.  If there was a market for this we would deffiantly have a foot in the door so to speak but in this case unless there is a significant demand its not likely as it would be too niche a market.  

If it ever does happen it will likely be on equipment built for this specific purpose, as the chipset running the device would have to support such features.

We will forward up though, because you never know, as ISPs get cheaper and faster the need for a back up may come up.

@meestermike I'm in the same boat. My wife and I work from home, as I wager more and more people will be doing now a-days, and need a back-up ISP. I purchased a 4G LTE modem with built-in failover thinking it would easily work with my Archer C4000 but I suspect the router does not like the static IP provided by my main/wired ISP vs. the dynamic IP provided by my wireless 4G ISP. But would love any input on how to acomplish this continuity problem.

@meestermike I don't think a request for such a featur would be unresonable for a Home product. We live now in an increasingly online world. People have cameras at home to keep watch on kids and helpers & for security, Our appliances are connected, Much study work is now online. Not to mention SM & entertainment requirements. Many people would be happily pay for such a feature.

TP_Link would do good to consider this open mindedly.

@Carl 

Here for the same reason.  I pay for virgin internet, it goes down from time to time.  I work from home sometimes too.  Im happy to pay for a separate 4g internet as a failover, and have a wan failover port.  Tplink are missing the point.... People buy their very expensive gaming routers because they care about performance and features, there are a lot of people that want a good setup these days.

Not much we can do about that I am afraid.  At least not on the home product side.  This is because home connections typically can only have one ISP delivered to the home at a time.  USB based backup requires software components and compatiblity that we do not currently offer in the US.  Manily because when we did have 3g/4g products here the comptaiblity was limited and broke everytime the ISPs updated the devices.  Your best be would be to have a 3g/4G hotspot and use it in times your internet goes down.
