Re: [Haggle-arch] Problems with the installation of Haggle

Hello Mirco,

I'll try my best to answer your questions, embedded below:

This is necessary as a limitation in how we are operating the cards
when in adhoc mode.  When in adhoc, we assign a static IP to the
interface as a calculated hash of the card's MAC address.
Unfortunately, this staticIP must be released via a Handle that
Windows returns to us.  If Haggle is killed it is unable to release
this Handle, and thus "repairing" the interface is the only way to get
rid of the staticIP and thus regain normal behaviour of the card.  We
are looking into ways to fix this in a more robust way.

This is the root of all your problems because if Haggle cannot
reliably set the adhoc mode it cannot operate correctly to exchange
information in p2p mode.

This seems to be a recurring problem on many devices that we have not
yet been able to figure out.  Apparently this is an issue for some of
the IPW2100 cards as well.  I am sorry that I currently do not have a
fix for this yet.  On some cards, if you copy line 435 and paste it
just before line 441, the setting of the mode AFTER setting the SSID
might work.  This seems to go against the official driver spec for
what should happen, but it might work.

I'll try to figure out what else I can do to remedy this.  In the
mean-time, please let me know what else you've tried that does or does
not work.
