Bug Description

After a fresh install of Xenial (16.04) on my laptop (Acer Aspire VN7-591G), the WiFi does not work after suspend. It worked without problem on the latest Trusty version (14.04.4).

The Wireless module is:

Network controller [0280]: Qualcomm Atheros AR9462 Wireless Network Adapter [168c:0034] (rev 01)

Steps to reproduce:
- Turn the computer on. Make sure WiFi is on and working.
- Suspend the device (e.g. by closing the lid)
- Wake the device up (by pressing the power button)
- Check the network connectivity

Expected result:
- WiFi can be used after suspend

Actual result:
- No WiFi indicators in the "Connections" menu after suspend. The device has to be restarted, or I have to log out of my session then log back in to get the WiFi connection indicators back (de-activating/re-activating the "Enable WiFi" or "Enable Networking" from the Network menu does nothing).

    Update (2016-05-05): In fact, the WiFi connection works properly (I can access the Web and I have an IP when checking with `ip addr`), but the network indicator doesn't reflect this, so it might be a Network Manager issue?
