Thanks for the tip. In my system the path to remove was below:

/sys/devices/pci0000:00/0000:00:1c.2/0000:02:00.0/remove
Also symlinked here: 
/sys/module/iwlwifi/drivers/pci:iwlwifi/0000:02:00.0/remove

I am now able to restore internet without system restart. Now I need to find a 
way to do this automatically whenever internet goes down.

Thanks,
Bala
