** Description changed: + [Impact] + Impacts all users of ipw2x00-based hardware, for the ipw2200 and ipw2100 drivers: this is fairly common Intel Corporation PRO/Wireless hardware present in at least quite a few Thinkpad laptops. + + + [Test Case] + On a system with an Intel PRO/Wireless card: + 1) Click the network indicator/applet. + 2) Observe the detected signal level. + 3) Try to connect to a secured wireless network. + + Connection should be successful and ask for the wifi network password + (if it's not already entered) + + Alternatively: + 1) Run the command 'nmcli dev wifi'. + + Signal level should be low (usually visible as simply '0'). + + + [Regression Potential] + This change will modify the detection behavior for the wireless framework to use for wireless cards. It needs to be properly tested with the affected devices to make sure the signal level and encryption capabilities are properly detected; but should also be tested with other devices to make sure signal levels and encryption capabilities remain properly detected. A possible regression scenario would be if a device that works with nl80211 (without the patch) would get detected as needing wext when it is not implemented. This would likely cause such a device to not be able to see wireless networks and connect to them. + + ---- + 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. 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 + 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 + 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.
