I have doing a fair bit of my own testing with this bug - whether this assists or not with a fix not sure, but here are my obseravtions.
Lenevo x220, latest iwlwifi driver [18.168.6.1], Ubuntu 16.04.1 (clean install), latest stable kernel 4.6.5, and latest Network manager 1.2.2-0ubuntu6. I can report the following: After Suspend then resume, fault still occurs. Also see nmcli below, output of Nm icon is the 2 vertical arrows (not the wifi symbol) and NO WIFI NETWORKS LISTED - but connected to wifi: xxx@xxx-ThinkPad-X220:~$ nmcli dev DEVICE TYPE STATE CONNECTION wlp3s0 wifi connected Lxxxx 1 enp0s25 ethernet unavailable -- lo loopback unmanaged -- HTH Cheers... xxx@xxx-ThinkPad-X220:~$ -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1574347 Title: [SRU] Re-read the link type if the name changed Status in NetworkManager: Fix Released Status in OEM Priority Project: Fix Released Status in network-manager package in Ubuntu: Fix Released Status in network-manager source package in Xenial: Fix Released Bug description: [Impact] NM needs to re-read the DEVTYPE after the device name changed, an example is that WiFi network list disappears from network manager applet [Testcase] 1. Boot the system. It should include a wireless device. 2. In a terminal, run 'nmcli dev'. 3. In the correct case, the line for the wireless device should read "wifi" under the TYPE column. In a failure case, it will read "ethernet". After upgrading to the new version, the repeating the above steps should give expected behavior. [Regression Potential] Potential of causing regression is relatively small for a one line change to re-read a value to be known. --- Problems:- 1. The network manager applet does not show the list of WiFI APs it can find. 2. The network manager applet does not the name of the AP to which it is connected 3. The icon of the applet shows two vertical arrows in opposite direction - the wired connection symbol and NOT the wifi connected icon. Temporary Workaround:- Log out and again log back in.
