Default Adhoc wifi

I have a Nokia E71 that I still use. I got a good offer for a data plan and I took it. I'd installed Joikuspot wifi hotspot tethering in it. What I want to do is to user the e71a an emergency wifi hotspot. It can be detected with my laptop in Adhoc connection, but for the life of me, I have not been able to make Adhoc connection work even after trying most of the methods that are known to work in other devices. It would be nice if someone could rewrite the wpa_supplement file so that Adhoc connections can be made possible.
