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.
