What is expected to happen is Network Manager populates networks within range immediately when ones laptop hardswitch is turned on, whether the ethernet cord is plugged in or not. 4) What happened instead is when the hardswitch is off, ethernet plugged in, one removes the ethernet cord, then within seconds turn the hardswitch on so the wifi indicator light is on, no networks are in range, even after waiting a few minutes. Please see screenshot.png for scenario where the ethernet cord is plugged in, wifi switch on and no wifi networks populate Network Manager. If questions exist, please ask.

Well, you have wireless disabled. If you switch it on by hardware switch, rfkill list should indicate that it's not blocked. The other thing is that in /var/lib/NetworkManager/NetworkManager.state WirelessEnabled should be true. Did you disable that by right-clicking nm-applet and unchecking "Enable Wireless"?
Jiri Klimes thank you for working together with me on this bug. > Well, you have wireless disabled. > > If you switch it on by hardware switch, rfkill list should indicate that it's > not blocked. > The other thing is that in /var/lib/NetworkManager/NetworkManager.state > WirelessEnabled should be true. Agreed. > Did you disable that by right-clicking nm-applet and unchecking "Enable Wireless"? No, I did not hover my mouse on/near nm-applet during https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/651571/comments/5

Changing /var/lib/NetworkManager/NetworkManager.state WirelessEnabled back to true should enable wireless again.
Any update on this issue Christopher? NM 0.8.4 fixes some issues with WiFi rfkill handling and user state handling.
Created attachment 186940 [details] /var/log/syslog Ubuntu 11.04
Dan Williams, thank you for following up. Ubuntu 11.04, NM 0.8.4 improved the situation as I am able to workaround the problem: With wireless hardswitch turned off, ethernet cable plugged in clean boot into a Ubuntu 11.04 Live CD. Immediately took copy of /var/log/syslog (please see attached /var/log/syslog Ubuntu 11.04). Disconnected ethernet cord then turned on wireless hardswitch but no wireless networks in the area. Performed the following via the Terminal: ubuntu@ubuntu:~/Desktop$ sudo stop network-manager network-manager stop/waiting ubuntu@ubuntu:~/Desktop$ sudo start network-manager network-manager start/running, process 5172 ubuntu@ubuntu:~/Desktop$ rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no Could see wireless networks in range and successfully connected. lsb_release -rd Description: Ubuntu 11.04 Release: 11.04 apt-cache policy network-manager network-manager: Installed: 0.8.4~git.20110319t175609.d14809b-0ubuntu3 Candidate: 0.8.4~git.20110319t175609.d14809b-0ubuntu3 Version table: *** 0.8.4~git.20110319t175609.d14809b-0ubuntu3 0 500 http://archive.ubuntu.com/ubuntu/ natty/main i386 Packages 100 /var/lib/dpkg/status
AFAIK the rfkill handling is totally different in 0.9.x and this bug report isno longer valid.
