Re: NetworkManager autoconnects to profiles in reverse order

Thanks for your reply, Beniamino.

Unfortunately no. I checked the Ubuntu backports for 14.04 (trusty), but there are no updated versions available. An upgrade to 16.04 LTS is not an option at this time.

I can report some progress in this matter though. I've just now made a small adjustment to the source code, and it seems to have fixed the issue. The last connected profile now autoconnects on boot. However, I am not a developer (my C knowledge is very limited) and what I've done might be extremely hacky and just plain wrong :) I could use someone with more insight into the network-manager source code to validate or tweak my simple fix. I made the change based on an educated guess, but I don't fully understand the inner workings of how the autoconnecting works. Any help in validating this is greatly appreciated.

This is the patch I made to nm-device.c:

This is probably a bug, but 0.9.8.8 is quite old; are there any newer
NetworkManager versions for your distribution that you can try?
