The problem is: when my friend creates a shared wi-fi connection in his Windows 7 box, my Ubuntu box sees that. It has two icons: wi-fi signal (as it is wi-fi) and a wired connection (so I don't understand why). But when I try to click on the name of the network in the list, nothing happens. The list just closes, that's all.
And when I create new wireless network in my Ubuntu box (now I plug the Internet cabel in and I need to share the Internet with my friend), my friend can't connect via his Windows 7 box. He says that password doesn't match, however the password is correct.
I think, maybe it's something wrong with password-secured connection? But I can't create unsecured network.
Well, looking forward for hearing from you, guys. Thanks!
