I also have a Dell Inspiron 6400 (a.k.a. E1505) with ipw3945. It worked flawlessly under Feisty.
An interesting note: since I upgraded to Gutsy, ipw3945 connects to networks that I don't want it to connect to. Some neighbour has a network with SSID "default". If ipw3945 connects to default before NetworkManager gets a chance to say "hey! connect to home_ssid!", I'm up a creek without a paddle. If, however, I restart ipw3945 and manage to click my home network in KNetworkManager *before* ipw3945 connects to 'default', I get normalcy. Or, one time, X froze. Anyway, do other people see this behaviour (connecting to open networks "automagically")? -- [Gutsy]Network Manager Applet can't connect wireless with ipw3945 driver https://bugs.launchpad.net/bugs/121439 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
