So I’ve got access to two networks, a wireless one on wlan0 and a mobile broadband one (with a 3G modem) on ppp0, and both have a tendency to be rather unreliable. I decided to look up bonding the two, and while I can sometimes manage to enslave wlan0, ppp0 always fails.
I’ve followed the information and guides from [1] and [2], as well as what Google could find (though most of the information there was seriously outdated). I did find a post on the BBS with exactly the same problem[3], and I tried what they had used, but it also failed.
Bonding works on ethernet links between your computer and a suitably configured switch (LACP should be best). For ppp links you can use multi-link ppp, but it needs to be supported on the other side too (and both of your ppp links need to connect to the same access server). but bonding wlan0 and ppp0 is not possible, and I don't even see what you expect to gain if both are unreliable. you might try playing with multi-path routing, so that you have a default gateway through both of your links, and packets alternate through one or the other. The linux implementation also supports "weights" that you can set according to the supposed bandwidth of the links. it also supports caching so generally packets of a single connection will go out from the same link. -- дамјан
