This bug occurs on my girlfriends laptop with 15.10 beta.

Symptoms: After suspend/resume cycle, wireless does not connect. rfkill
list shows that it's hardware blocked (but no hardware switch present on
device).

What works on this laptop is (from the brain, so no guarantee for exact module name):
rmmod -f iwlmvm
rmmod -f iwlwifi
rfkill unblock all
modproble iwlwifi

If you need additional info I can provide it.

Title:
  network disabled after suspend - resume

Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  Background: 
  this started to happen after the upgrade to Utopic Beta 1

  3) When I close the laptop's lid and open, the wifi should reconnect
  4) Wifi does not reconnect. It says "Wi-Fi networks" - "disconnected" when I left-click on NM icon in notif area. However the context menu (right-click) has items "Enable networking" and "Enable Wi-Fi" both with checkmarks.

  Workarounds: 
  switch off - on the physical switch on laptop OR  two times go and select "Enable networking" in the NM context menu (after first time it removes checkmark and the  "Enable Wi-Fi" item - visual feedback of being disabled).
