I can confirm this also. I just upgraded to Gutsy, everything wireless was fine in Feisty, but the network manager lags and hangs and won't switch wireless networks and often won't connect (or takes forever) and freezes eventually if I try to do too much with it.
I've tried reloading but for me it takes a complete reboot. Often when it freezes I have other strange issues like I can't open system monitor or a terminal session. I've got Intel PRO wireless 3945 ABG as well. -- wi-fi connection goes down - reboot is required https://bugs.launchpad.net/bugs/154549 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
