The suspension was working perfect in Kubuntu 11.10. When I upgrade to 12.04, I get an issue with wireless network after wake up from suspension. The first 3-4 suspensions the wireless still working, but after that the wireless networking will be disable. Though I can plug in the cable in login in the network. I try to restart network-manager service without result. After I reboot the computer the wireless networking come back again.
