Public bug reported:
Binary package hint: kdebase-workspace
Affected component: KNetworkManager
Setup:
Dell Vostro 1500, Core 2 Duo, nVidia GeForce 8400M (not currently used)
Installed Hardy alpha 6, KDE4
To save someone 5 minutes of head scratching, I'll repeat: that's KDE4,
not KDE3. However, looking through the /etc/init.d/kdm script, I see
references to kde3, so not sure ...
Symptom: Unable to connect to wireless network. Pop up notification
message does not move beyond "Activation stage: Configuring device."
Background:
* If I do this from the command line, I am able to connect to this same
wireless network and get upgrades from the internet, etc.
* This wireless network is unencrypted and open. (Security is MAC
address-based.)
* This wireless network does not broadcast its SSID. (For giggles, this
wireless network's SSID is 'YosemiteW'.)
* Wireless interface is apparently nickname wlan0 on this machine
* $ lspci | grep Wireless
0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network
Connection (rev 02)
* $ apt-cache policy knetworkmanager
knetworkmanager:
Installed: (none)
Candidate: 1:0.2ubuntu1-0ubuntu12
Version table:
1:0.2ubuntu1-0ubuntu12 0
500 http://us.archive.ubuntu.com hardy/main Packages
Steps to reproduce:
1. Right-click on KNetworkManager icon in System Tray
2. Select "Connect to Other Wireless Network..."
3. Manually type in YosemiteW in "Name (ESSID)" field
4. Click Connect.
... Popup notification bubble named "Activating Wireless Network Connection"
stops at 28% ...
... Extra text: "Activation stage: Configuring device."
$ iwconfig wlan0
... ESSID:"YosemiteW" ...
... Access Point: Not-Associated ...
5. After some timeout time, popup notification bubble changes to
"Connection Failure"
Workaround:
1. $ sudo iwconfig wlan0 essid YosemiteW
# happens almost instantaneously
2. $ sudo dhclient3 wlan0
# a couple of warnings: "wmaster0: unknown hardware address type 801",
# then it connects. Whole step takes about 3 seconds.
