3) After resuming from hibernaton I expected the wireless for a light to lit up on the wireless networking button and for the wireless networking to resume by connecting to the wireless router.

4) Light of the wireless button on the computer did not lit up and network-mangager icon reports no connection. Clickin on the icon does not report any wireless network and if I right click the icon the activation selection box for wireless network is grayed out.

It seems that after resuming from hibernation wireless networking is disabled.

lshw -C networking returns

*-network DISABLED

Wireless network can not be turn on by pressing the wireless network button of the computer and the light on the button remains off.

Outputs for common wireless debugging commands can be found from the attachments. OK on file name indicates before hibernation with functioning networking and fault indicates after resuming from hibernation

suspend is not affected and the computer resumes from suspend with out problems.
