Wireless connection disconnected after hibernate or suspend

Hibernate/suspend turns off the power in the computer and saves the current state into memory. It doesnt save current connections. The way to get it back is to set it to connect automatically. This isnt a real problem and doesnt really need correcting. If you want you can file a bug report.

You can restart network connections by typing

sudo /etc/init.d/networking restart

this should effectively reboot your network connections. Hope this works for you too
Good luck and regards from
Tom :)

Hi Everyone,

With the Ubuntu Jaunty Jackalope 9.04 Beta release [1], the Ubuntu
Kernel Team would like to request your assistance with suspend/resume
testing. The team has been gathering information about Ubuntu's
suspend/resume support for varying pieces of hardware. If you would
like to participate and volunteer to perform tests, the Ubuntu Kernel
Team has provided a suspend_test script [2]. The script has been
packaged with checkbox 0.7 and should be available with the Jaunty 9.04
Beta release. The script will perform a number of suspend/resume tests.
The first few tests will require human interaction. In total, the tests
should take approximately 30min to complete and will perform 34
suspend/resume cycles. For information on how to run the script and
other details, refer to the SuspendResumeTesting wiki [3].

Test results are also being tracked on the Ubuntu wiki [4] so please be
sure to add any information for hardware that is not yet listed. Also,
feel free to include any additional information for hardware that is
currently listed. In the event that a test should fail, hooks have been
added to apport to automatically detect failures and subsequently file a
report in Launchpad. Upon rebooting the system after a failure, apport
will try to gather as much information from the system and guide one
through the bug filing process. Please be sure to also visit the
corresponding debugging page [5] which documents additional requested
information that apport is unable to gather. Please include this
information in the bug report as well.

The team appreciates all the time and feedback that can be dedicated to
suspend/resume testing and reporting. Please let us know your results.

Thanks in advance,
The Ubuntu Kernel Team

I was wondering what was going on with that.
