How to bond two seperate DSL connections to create one faster internet

Hello and I hope you are having a good day. I am trying to figure out if it is possible to combine two sepearate DSl modems and bond them to create one faster internet connection. I live in a place where I can only receive DSL from one provider (Windstream) and the fastest speed I can buy is 3mbps download and .5 mbps upload. I live between my father-in-law and my brother-in-law and both of them have their own sepearate internet connection.

I connect to my father-in-law via about a 330ft cat5e direct burial cable that is in the ground. I do acheive full connection speeds of 3mbps and .5mbps using this setup. I can also connect via wifi although if this was the chosen route for bonding I would need to buy an outdoor antenna (like the one below) to increase the signal.

I can connect to my brother-in-laws internet via wifi although I would need to buy an outdoor antenna to acheive better signal.

My current hardware
Dir-655 with Rosewill 3x5dbi antenna attached (I use this antenna to get better signal outside to my metal storage building, I can get decent signal inside even with the storage building door shut using this setup)
I also have a couple Gigabyte switches and plenty of ethernet cable.
Father-in-law has a windstream modem with wifi. It is a 2wire 2701HG.
Brother-in-law has an identical winstream modem-2wire 2701HG.

What would I need to purhcase in order to bond these two internet connections to create one faster (hopefully 6/1mbps) internet connection?
I believe I would need a router with a dual WAN but am unsure which one to buy. Also where I would connect to my brother-in-law's internet I would need to buy a access point and outdoor antenna so I can send the signal to the 2 wan router, correct?

My father-in-law is about 300 feet away from where I would probably put an outdoor antenna although I could put the antenna on the otherside of my house and make it about 250 feet.
My brother-in-law is about 200 feet in the other direction away from me.
If my directions in my mind are correct my father in law is about due south of my house and my brother in law is about due west of my house.

Is this too much work to get involved in or way too complicated or too costly? I'm willing to spend a few hundred dollars on it but if it is going to cost alot I probably will just deal with it. I have a basic understanding of networking just not alot, but I would really like to get a faster internet connection due to the fact I work on computers from time to time and I download large files and would really like it to be faster.

I am not really too interested in setting up a sever unless it is necessary as I believe there is a router that can handle all that for me. However if this is necessary I already have a computer I can use plus I believe I can get access to windows sever installation and product key (I have a technet subscription).

After this setup I would probably send the bonded signal out so that both my father and brother in law could have access to faster internet. Any ideas on the best way to do this?

If I missed this and this has already been answered I'm sorry but I did not see anything that was a few years old and that completly answered my quesitons. Please also let me know any additional info that you may need. Thanks for your help, sjonesy.

Hey sjonesy,

I noticed that nobody seemed to get back to you even though this post is a bit old. However, I've been doing some research and you actually can combine multiple Internet lines (eg including a cable modem) to make a faster and more reliable one. The Internet lines can be different technologies and can come from different providers, and it is not necessary to have special software (e.g. MLPPP) or hardware at the provider premises - they don't even have to know you are bonding their line to another (it is done at layer 4).

For example, you could bond together four ADSL lines at 6Mbps down/ 768k up to create a 24Mbps down/ 3Mbps up connection, even for a single file transfer or a streaming video source. This is a lot cheaper than a bonded T1 line.

I'm sure if you google search for "broadband bonding" you'll find what you're looking for.

Hope this helps your search.

Hey sjonesy,

As far as a particular model/company that could handle bonding for you, I would highly recommend mushroom networks. I've had some great interaction with them as far as bonding and reliability of products. I have experienced bonding with their products without communication with the ISP and I have actually told some friends/clients about their services. For personal use, it might be a little more pricy, but I feel like you should still look into it. If you give them a call or email, I'm sure they could explain it much better than I can.

Hope this helps!
