Wifi Stops Working After Suspend

[Aakash Dabas]

My wifi works before suspending the ubuntu but right after I login after suspension wifi doesn't works. It always displays hard blocked but the thing is that the hardware key doesn't works here. The possible solution is to restart. I've also tried following commands:
nmcli nm wifi on (NO EFFECT)
service network-manager restart (NO EFFECT)
rfkill ublock all (NO EFFECT)
I've also updated my ubuntu to latest and also updated the drivers. But non of them works.
I've also contacted my network driver providers. They are saying that this is a problem with the kernel and not with the driver.

One more thing after using logging in again, wifi network manager doesn't responds and rfkill event shows following output on pressing the wifi hardware key,

 idx 2 type 1 op 0 soft 0 hard 1
 idx 2 type 1 op 0 soft 1 hard 1
 idx 2 type 1 op 0 soft 0 hard 1

it changes the software lock but not the hardware lock. After restarting the ubuntu everything again starts functioning properly.
