Today I was creating an Ad Hoc network for sharing internet connection and I realized it is not working... I have done it before on Ubuntu 10.10, now on 11.04 it just doesn't work. I create a new connection (Create New Wireless Network) and it is never visible to the other computers (I checked the IPv4 settings, it was Shared to Other Computers).
I really do not know what is going on, my wireless card is working perfectly fine (I can connect to other network and on additional driver it is there with a green circle)...
Any help will be welcome!
