Daniel, ricardisimo, if you're still having issues, please file separate bug reports, using 'ubuntu-bug network-manager', so that all the relevant information about your wireless hardware is available. Don't forget to comment here with the bug number so I can take a look at it.
The issues on 9.04 with the ipw2200 hardware are likely specific to WPA, and AFAIK they were fixed since in newer releases, so I would suggest upgrading to a newer release (especially since Jaunty is EOL since October 23, 2010). Because the release is EOL and further issues are definitely visible on other hardware and other releases (but don't include enough information to suggest it's the same issue), I'll mark this bug Invalid. ** Changed in: network-manager (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. https://bugs.launchpad.net/bugs/366217 Title: Intel PRO/Wireless 2200BG Fails to connect to any network -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
