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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1348801 Title: [HP Pavilion dv6-1390ev] Wifi network fails to come online after resuming from suspend Status in “linux” package in Ubuntu: Confirmed Bug description: I am primarily connect using wifi, so after i close the lid of my laptop, and then open it back again, i find wifi connect won't come online and upon selecting enable networking nothing happens, so the only solution is to reboot.
