Connecting Ubuntu 10.04 LTS to an Ad-Hod Wi-Fi Network in Windows 7

Question

WiFi

Hi all!

There is a laptop (Ubuntu + Windows 7), desktop (Windows 7) + wifi whistle from D-link.
A Wi-Fi Ad-Hoc network has been created on the desktope. Internet fumble on the Wi-Fi interface.

From under Windows, from a laptop it connects perfectly, the Internet is rummaged around everything works ok.

Actually, the problem is that when connecting from Ubuntu to the network, the Internet connection periodically disappears (breaks with a frequency of 2-3 min.)
At the time of the break, Ubuntu network manager shows that the connection is active, but there is no ping. And in Windows 7 it shows that there are no connected computers. A couple of minutes pass and in 7 it shows that there is a connection, and at that moment everything works in Ubuntu. Again a couple of minutes and disconnect. And so constantly. Tried deleting network-manager/gnome and installing wicd didn't help. wicd does not want to connect at all, it comes to getting an IP, hangs like that for a couple of minutes and falls off.

Here is what iwlist scan looks like: Here is iwconfig:

Answer 1

I had the same glitches on xp, on 7-ke it was not. I could not find a solution to the problem, I spat and put a virtual machine on Windows and debian in it (fortunately, it only needs 32 MB of memory).
