[Bug 1348801] Re: [HP Pavilion dv6-1390ev] Wifi network fails to come online after resuming from suspend

 

It appears that your system firmware is for some reason deciding to
apply a so-called "hard block" to the wireless. Based on the rfkill
command output you supplied it looks like all you should need to do is
push the wifi toggle button to reverse the state to get your wireless
back. The next time this happens check that 'rfkill list' shows the
"Hard blocked" state of hp-wifi and phy0 as "yes", then press the wifi
toggle button and confirm that the states change to "no". If both the
soft and hard blocked states for these devices are "no" then network
manager should attempt to connect to wireless, assuming that the "Enable
Networking" in the network indicator hasn't somehow become unselected.
The step of updating the password in the network settings should not
make any difference.

Fixing weird firmware behavior like this can be challenging. About all I
can do is take a look at the ACPI tables and see if I can find anything
there. If you'll run 'sudo acpidump > acpi-tables.txt' and attach acpi-
tables.txt here I'll see if I can figure anything out.
