This bug also affects Xubuntu 12.04. Reverting to the previous kernel, 3.2.0-23, resolves the issue.

If I reboot into 3.2.0-27-generic this problem does not occur. I am using a Toshiba Equium M70-339 laptop, and my wireless card is listed on the manufacturer's webpage as being an Intel® PRO/Wireless 2200 LAN Mini PCI adaptor integrated in Intel® Centrino™ mobile technology. I've purged and reinstalled network-manager to no effect. The only way for me to get the signal strength reported by the nm- applet is to use an earlier kernel. iwconfig reports the correct signal quality. lsb_release -rd Description: Ubuntu 12.04 LTS Release: 12.04 apt-cache policy network-manager network-manager: Installed: 0.9.4.0-0ubuntu4.1 Candidate: 0.9.4.0-0ubuntu4.1 Version table: *** 0.9.4.0-0ubuntu4.1 0 500 http://mirrors.coreix.net/ubuntu/ precise-updates/main i386 Packages 100 /var/lib/dpkg/status 0.9.4.0-0ubuntu3 0 500 http://mirrors.coreix.net/ubuntu/ precise/main i386 Packages apt-cache policy linux-image-3.2.0-29-generic linux-image-3.2.0-29-generic: Installed: 3.2.0-29.46 Candidate: 3.2.0-29.46 Version table: *** 3.2.0-29.46 0 500 http://mirrors.coreix.net/ubuntu/ precise-updates/main i386 Packages 500 http://mirrors.coreix.net/ubuntu/ precise-security/main i386 Packages 100 /var/lib/dpkg/status I expect nm-applet to display the signal strength of my WPA2 wireless AP, but instead no signal is reported.
