I have Ubuntu Xenial(16.4.0.2) installed and unable to find wireless
networks to connect to. Wireless switch is on and wireless networking is
enabled and the device is in a up state

This is a dual boot system and when I boot with Windows 10, I am able to find
wireless networks and connect successfully with the same hardware.
Tried workaround mentioned in How do I get a Realtek RTL8723BE wireless
card to work? but did not help.
Ubuntu is able to find wireless connection at home without any problem.
When I go to a library, that's when Ubuntu fails to pick up any wireless
network.
Rebooted Ubuntu and captured syslog messages when I was in a library. Syslog
messages available at
