I still have the problem and I have maybe identified a culprit. in journalctl -xe, I have seen : ● wifi-resume.service loaded failed failed Restart networkmanager at resume
-- L'unité (unit) NetworkManager.service a commencé à démarrer. janv. 26 19:43:09 XPS kernel: nfs: server newnas not responding, timed out janv. 26 19:43:15 XPS kernel: nfs: server newnas not responding, timed out janv. 26 19:43:39 XPS kernel: nfs: server newnas not responding, timed out Looks like a timeout on my NAS Synology. NFS shares are mounted using autofs. Looks like at resume it tries to reconnect before having the connection ? Don't know how to fix it. But it may ring a bell for you. -- 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/1636282 Title: network-manager after suspend showing arrow icon instead of wifi icon and showing no wifi networks Status in network-manager package in Ubuntu: Confirmed Bug description: As requested by Mathieu Trudel-Lapierre (cyphermox) in bug #1589401 I'm creating my own bug report. 1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu $ lsb_release -rd Description: Ubuntu 16.04.1 LTS Release: 16.04 2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center $ apt-cache policy network-manager network-manager: Installiert: 1.2.2-0ubuntu0.16.04.3 Installationskandidat: 1.2.2-0ubuntu0.16.04.3 Versionstabelle: *** 1.2.2-0ubuntu0.16.04.3 500 500 http://ch.archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages 100 /var/lib/dpkg/status 1.1.93-0ubuntu4 500 500 http://ch.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 3) What you expected to happen I'm connected by WiFi only, not by a wired connection. I expect to see the WiFi icon anytime while being connected to my WiFi network. Also, I expect to see all the WiFi networks around me (at least one other network with good reception and about 3 with bad reception). 4) What happened instead After waking up the laptop from suspend, there appears the ethernet icon (arrow symbols) instead of the WiFi icon. Also, in this state there are no other WiFi networks visible in the network-manager. However, the laptop is still connected with my WiFi and the connection works as usual. Using "service network-manager restart" in the console I can get the wireless icon back and all the other networks around me are visible again. This can be reproduced anytime and with 100% "success rate". The problem appeared with Ubuntu 16.10 and was persistent since.
