[Seth Forshee <seth.forshee+lp@xxxxxxxxxxxxx>]

In the logs attached to the bug I see two suspend/resume cycles. In the
first it looks like you reconnect to wireless just fine. In the second
it looks like you do not, and in that case I see the RF_KILL messages.
Did you do anything which might cause the firmware to toggle the rfkill
state after you resumed, like tapping the wireless hotkey?

Next time this happens, please run 'rfkill list' and note the states of
the blocks. Then click on "Enable Networking" in the network indicator
and run the command again. Finally press the wireless hotkey toggle and
run the command one last time. Then paste the output from all three runs
here. It would also be useful if you could run 'tail -F /var/log/syslog'
in another terminal and watch it while doing all of this to see whether
or not the RF_KILL messages appear in direct response to something you
do.

Thanks!
