[Bug 1516852] [NEW] wireless connection drops despite full signal
Public bug reported:
This has been an issue since 14.04, but it is much more frequent now.
I have an issue where, despite seeing a full signal, I have no
connection. when I try:
ping -c 5 google.com
I get
ping: unknown host google.com
and nothing that requires an internet connection works either.
But this works:
ping -c 5 127.0.1.1
PING 127.0.1.1 (127.0.1.1) 56(84) bytes of data.

Once I toggle the hardware off/on, it works again without issue.
