try this:
Here is a technique that works for many. Please open Applications > Accessories > Terminal and do:
Code:
sudo lshw -C network
You will learn details about your wired and wireless card. For example, here is my wireless detail. You need the exact name of your wireless driver.

configuration: broadcast=yes driver=iwl3945 ip=192.168.1.108
Next do:
Code:
sudo gedit /etc/pm/config.d/config
The text editor gedit will open. Type in:
Code:
SUSPEND_MODULES="iwl3945"
Substitute the driver name you found. Proofread carefully, save and close gedit.
Suspend and report your success.
I have a sony vaio vpc and have experienced the same problem. One thing that seems to work consistently is turning of my wireless before I suspend. My laptop has a button for this, so I just have to flick the switch. When I come back from suspend, I turn the wireless back on once I have logged in.
Perhaps you simply need to restart your network manager.
sudo systemctl restart NetworkManager
