Hello,
I would like to use the bonding option.
If i have two wireless source, will have maybe a third one.
How many wifi card i will need ?
I want to add the two connection in one, and repeat it all from an ubuntu.
And.. will it increase the bandwith ?

This is my "idea" scheme :

WIFI 1 CHANNEL 1 10MBS = wlan0
WIFI 2 CHANNEL 2 2MBS = wlan1
WIFI 3 CHANNEL 3 1MBS = wlan2

--->bond0

bond0 --> AP (wifi 4 channel 4) --> bonded interface, 6MBS !

I guess it works partially. Will it work with torrent server ?
what the "load balance" can do ?

Thanks

That may not do what you think it will:

Note that I don't know for certain that the answer on the above link is absolutely true but as far as I understand it you won't get much benefit from multiple WiFi cards as they'll be competing with each other for bandwidth.

that i know it's been a year i'm looking to know if it's possible or not. people who says yes (especially for load balancing two connection for download torrent faster) never answer...

Firstly your only looking at one end of the connection, what will be on the other end?
Second in the 2.4GHz range you can have a total of 3* clear channels working as some of the channels overlap.

It would be better if your stuck with wireless to simply have the best possible WiFi standard in use with the best possible hardware and least obstructions between the endpoints.

The basic ways to use more than one nic is either have software on both sides that combine all to act like a single nic. Intel has that but I don't know of any wireless that do but may be some way.
Another way is to split by some means how the network acts. Either by application with a very advanced firewall or by using ip ranges to set path for each nic to share load.
