I had the same problem: after upgrading from Kubuntu Jaunty amd64 to Kubuntu Karmic Beta amd64, I couldn't connect to my wireless (rtl8187 usb stick). My SSID was always hidden, and in Jaunty this never was a problem. I just made the SSID public and I can connect.
I did try by the way also Wicd, the gnome network manager and the default knetwork manager, but all could not connect to the hidden SSID. So it doesn't seem to be just an issue with the default network manager. There is some underlying problem. -- knetworkmanager won't connect to hidden WiFi AP using WEP https://bugs.launchpad.net/bugs/444262 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
