Tommy_CZ, this bug was reported a while ago and there hasn't been any activity 
in it recently. We were wondering if this is still an issue? If so, regarding 
your Bug Title:
>"Wireless and graphic drivers disabled after upgrade..."

While these two problems occurred after the single event of upgrading, this is 
a result of the problem, not the cause. While both of these problems may end up 
having the same single cause, because wireless and graphics are two completely 
different hardware pieces, with different linux (Ubuntu) kernel drivers 
involved, we should split this problem into two different reports; one for the 
wireless (this one), and another for the graphics. For more on this, please see 
the Ubuntu Bug Control and Ubuntu Bug Squad article:
https://wiki.ubuntu.com/Bugs/BestPractices#X.2BAC8-Reporting.Focus_on_One_Issue

and Ubuntu Community article:
https://help.ubuntu.com/community/ReportingBugs#Bug_Reporting_Etiquette

For the graphics issue, could you please execute the following via a terminal, 
and feel free to subscribe me to it:
ubuntu-bug linux

As well, could you please test for this with the latest development
release of Ubuntu? ISO CD images are available from
http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following 
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional 
upstream developers to examine the issue. Please do not test the kernel in the 
daily folder, but the one all the way at the bottom. Once you've tested the 
upstream kernel, please comment on which kernel version specifically you tested 
and remove the tag:
needs-upstream-testing

This can be done by clicking on the yellow pencil icon next to the tag located 
at the bottom of the bug description and deleting the text:
needs-upstream-testing

If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If you are unable to test the mainline kernel, please comment as to why 
specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

Please let us know your results. Thank you for your understanding.
