This bug seems a bit of a gripe session that nobody has paid attention to. However, I can confirm at least some of the behavior here with release Feisty. Since the Ubuntu world doesn't seem up-in-arms about it, I assume it only triggers on some hardware. So please everyone, state your hardware. I'm on an IBM T40 with the Cisco aironet wireless mini-PCI card. The card works perfectly, including WEP, if I manually configure things with ifconfig, iwconfig, and route. Sadly, I don't know how to configure DHCP connections this way. I also move around a lot, so it's not a good solution. I also set my MAC address, so manual seems my future (FEATURE REQUEST: please let us set our MAC address, for privacy's sake! It's not hard...). Most of the time network-manager works for DHCP unencrypted sessions.
That's the good, here's the bad: 1. network-manager does not ever work with wep. 64-bit, 128-bit, ascii, hex, all fail. 2. Occasionally, the screen and mouse will freeze when using nm. Usually this happens after trying to mix nm and manual config, or a lot of suspends. A power-off is necessary (not sure if I could ssh into the machine, but switching ttys or killing X or rebooting with different 3-key combos don't work). 3. Often, particularly after a suspend, the "network radio active" light goes out, and then no wireless networking happens, period, even non-encrypted connections that used to work. On Thinkpads in Windows, you can press Fn-F5 to turn on and off the wlan and bluetooth radios. LED indicators come on and go off in response. Linux tends to keep the wlan indicator on all the time, and the keystroke doesn't toggle it. However, the bluetooth light and radio are toggleable through the ACPI interface (/proc/acpi/ibm/bluetooth). The corresponding wlan file doesn't exist. There is a file called /proc/acpi/ibm/wan that could be the equivalent, but it says "disabled". There should be a file here that controls the radio (turns it on and off). None of the manual commands ifconfig, iwconfig, lsmod, modprobe, rmmod, or route affect this light and its functionality. If a halt or suspend command is given when the light is out in this manner, the halt never happens because of an error: glup kernel: [88622.380000] unregister_netdevice: waiting for eth1 to become free. Usage count = 23 Eth1 is the wireless radio. No manual commands free it. The computer stays up while this message appears every few seconds until you tire of it. The original posting's problem 1 and the previous posting's problem 3 seem related to nm turning off the radio, or to a suspend or hibernate not turning it back on properly. That could make it a Thinkpad, aironet or combination bug, which few would have seen. It's pretty debilitating if you have to use wep, so I hope it's fixed soon. --jh-- -- network-manager multiple problems https://bugs.launchpad.net/bugs/91558 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
