This bug should be a interaction between this kernel fix:
http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-
precise.git;a=commit;h=d5b65f764c414a8da02c479f7fa57cfaee603fd3 and nm
on Ubuntu. Mathieu is going to handle this in network-manager as we
talked on IRC (#ubuntu-kernel/freenode). Marking the linux task invalid.

Title:
Kernel update on 10 Aug 2012 affects nm-applet signal strength
Status in “linux” package in Ubuntu:
Invalid
Status in “network-manager” package in Ubuntu:
Triaged
Bug description:
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.
