Networking does not work on laptop resume from suspend

[stevenospam]

I have a Dell Inspiron 7000 and am running Feisty with all the fixes applied. When I boot, my WiFi card (Dlink Air DWL-650) connects to the router and all is well for Samba and other network traffic. When I close the lid of the laptop, the system seems to suspend correctly. When I open the lid, the system starts up where I left off but I no longer have networking. ifdown and ifup for eth0 don't help and I have to reboot to get the network back. I've searched the forum on this and have done other Google searches but haven't seen a solution.

Thanks!

As you can see, the wireless settings were lost.
