I have the exact same problem on IBM Thinkpad x201 with Intel iwlwifi driver using open wireless N access point. It usually takes one resume cycle for the bug to appear. The network manager shows the wifi access point as connected. However, once this happens the laptop wireless netwroking completely stops, can't ping anything after. The only way to resilve this is to reboot the computer. Switching the wireless on/off in network manager does not help, restarting the network manager does not help.
I have also tried every kernel version (3.2.x, 3.4.x and 3.5RCx) with no success. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/996205 Title: Networking stops working after resume in 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/996205/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
