[Bug 1447864] [NEW] AR9462 wifi won't work after upgrade to vivid

Public bug reported:

After upgrading to Vivid, wifi wouldn't work tough cable connection is ok. I have a Atheros AR946 adapter.
Switching back to upstart, however, seems to solve it completely. Systemd is taking painfully long to start also, so maybe this indicates there is some trouble with it.
Also, I have kernel 3.16 installed instead of 3.19, for some unknown reason.

This is taken while booted from systemd. I am on cable now.
