I am on 16.04.1, and I too am having this issue. Whenever my laptop (W520) goes into Suspend or Hibernate mode and I boot it back up, the WiFi icon displays the "disconnected" message briefly, and then reconnects--only to display the up and down arrows associated with the Ethernet icon and the Ethernet drop-down menu in the top panel. No SSIDs are shown, and the menu asks me to connect to a WiFi network even though I'm already connected to one.
I have Thinkpad 11 bgn WiFi. Ubuntu displays it as "Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)". Device name is wlp3s0 rather than wlan0. -- You received this bug notification because you are a member of Desktop 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.
