Hi,
I think that if you hibernating/ suspending laptop, kernel doesn't store an iface configuration (unless it is static IP) and you have to send a request DHCP server after resume. Note, that a validity of assigned IP during suspend can expire and after resume you have to send the request to DHCP server anyway. Usually NetworkManager automatically send the request after resume. If you don't have it installed, you have to write your own acpid script which send request to DHCP server or do a network restart.
