Comment 0 for bug 1035590

With 3.2.0-29-generic the nm-applet no longer reports the wireless signal strength. 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.

I expect nm-applet to display the signal strength of my WPA2 wireless AP, but instead no signal is reported. This behaviour is only observed with the newest kernel.
