Thank you, @matzipan.
I also had this problem since upgrading to kernel 4.4 on linux mint 17.3
(ubuntu 14.04.03 derivative).
Removing `laptop-mode-tools` fixed it instantly for me, as well.
Good luck!

Hello everyone.
I had a similar issue on elementary OS freya when coming out of suspend
with Intel Wireless-N 7260.
I could patch it with "nmcli nm sleep false" , however, it seems like
uninstalling laptop-mode-tools fixed it definitively.
Also, this fixed another issue: after I issues a suspend

I have the same problem with Ubuntu 14.04 on Dell. Didn't have it with 12.04.
I tried a lot of things too with no luck.
sudo killall wpa_supplicant after each resume seems to fix it too.

A while back, my wifi connection kept dropping. I had to keep re-
booting Ubuntu 14.04 to try and get my wifi connection back. I have a
Lenovo Thinkpad X220T laptop with Intel Centrino Advanced-N 6205 wifi
card. I'm using a WPA2 connection.
I tried disabling the N mode of the wifi card, as detail
I had the same problem.
And I tries several fixes.
Something helped me (it seems)...
Symptoms:

interface wlan0 not configured

# lshw -C network

Probably this resoled the issue:
# gksu gedit /etc/pm/config
Sorry I meant to say that this affected me since upgrading to Xubuntu
15.04 (not 14.04).

I did the Sudo gedit /etc/pm/config.d/config and added the line:
SUSPEND_MODULES="iwilwifi" but used my wireless driver card instead of
the "iwilwifi" to fix this issue. I am running Cinnamon in ubuntu 14.04
though. Hope you resolved your issue by now.

In reference to Milton's comments (and thanks for the follow-ups) - my

That indicates a different solution might work - replace "killall
wpa_supplicant" above with "nmcli nm sleep false". I haven't tried it
