Also further to #60, I have put the following in mine (Thinkpad X1 Carbon 3) and it does indeed seem to fix the problem so far - been testing over a few days:
/lib/systemd/system-sleep/wpasupplicant: post) (sleep 3 ; /sbin/wpa_cli resume) & ;; 16.04.1 fresh install, kernel 4.4.0-59; network-manager 1.2.2-0ubuntu0.16.04.3 Anything shorter than 3 seconds seems to be too fast for that race condition; could this suggest this might be better fixed with a systemd dependency? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1585863 Title: WiFi malfunction after suspend & resume stress - sudo wpa_cli scan required to fix it.
