########## wireless info END ############
This is an issue with newer HP Notebooks running newer Intel wireless cards. Blacklist "acer-wmi" and "acer-wireless" in /etc/modprobe.d/blacklist.conf.
Add the lines
blacklist acer-wmi
And reboot.
Ubuntu tries to load the acer-wmi and wireless module which erroneously blocks the wireless.
Edit: if the wireless card/firmware continues to fail, please run the command:
dmesg | grep iwl
And edit your question with the output.
