I have notebook Lenovo Z500, his wireless hw: Centrino Wireless-N 2230 (vendor - Intel). When I close the lid notebook suspends and when it is woken up wifi is disabled and there is no way to enable it. rfkill says that it is hardware blocked. I've tried to restart network manager, added iwlwifi module to SUSPEND_MODULES in /etc/pm/config.d/config, but only rebooting helps. On Win 7 everything is fine. Are there any ways to solve this problem? It's very annoying. My Ubuntu version is 14.04 LTS

lsmod | grep wmi output:

snd_rawmidi            30144  1 snd_seq_midi

snd_seq_device         14497  3 snd_seq,snd_rawmidi,snd_seq_midi

snd                    69238  17 snd_hda_codec_realtek,snd_hwdep,snd_timer,snd_hda_codec_hdmi,snd_pcm,snd_seq,snd_rawmidi,snd_hda_codec,snd_hda_intel,snd_seq_device,snd_seq_midi

Thanks in advance

According to your comment, you solve the problem by manually issuing rmmod iwldvm && modprobe iwldvm. In order to get it to work automatically after a resume, you need to create a script.

I will adapt the instructions posted in this answer to suit your needs. Run:

gksu gedit /etc/pm/sleep.d/20_fix_wifi

Add the following content:

case "${1}" in
    resume|thaw)
        rmmod iwldvm && modprobe iwldvm
;;
esac

Save the file and reboot. Try to suspend and resume to see if it works.
