Combining Wifi connections

I have tried and sucsessfuly combined the bandwidth of multiple wireless network interfaces. My experiment consisited of two remote routers. number 1, was my own, and number 2 was at my friends house across the street who was willing to participate in the test. I used a spare computer to do the tests.

Each router was connected to an estimated 2MB sevice from the ISP. Both ISP's were different.

I used 2 PCI Wifi cards, and connected each to a seperate yagi antenna.

I used a piece of software called Midpoint 5.0, although it works well, it seems this is very hard to find on the internet. The company who made it seems to have abandoned it... and is making other products. However if you wish to spend the time, you will find some mirror server still hosting it.

Midpoint is effectivly a NAT tool, so it derives the adapters unique ip adresses, to the local machine. Midpoint can support upto 8 wifi cards, and you can set parameters dedicating cards for outbound or inbound traffic, or parralell, or even failsafe.

After setting up Midpoint, the two cards were able to connect to each of the routers. I ran several download tests, and speed tests and midpoint displayed a speed of 4000kb/sec

this was good to know, as it meant that for more bandwith, i just had to find more NICs and more AP's

The beauty of Midpoint 5.0 is it can be configured so that the computer its on acts as a proxy, thus sharing your combined bandwidth across your lan.

You could even be really cheeky and have for example, 2 fully connected leech nodes, each node would be equiped with 8 wifi cards each connected to its own AP, then setup as a proxy. Each computer is then hardwired into another computer with midpoint, but equiped with ethernet adapters, and the bandwidth from both leech nodes is combined!

That would be interesting to try.

Anyone else done anything on these lines?
