Bug Description

On a eeepc 1000h.

After hibernate/resume wifi card every odd time is dead.

It shows up, but it cannot connect to the network nor scan for the available access points.

This happens either with rt2800 + rt2x00 or with the rt2860sta driver.

wifi resume was fine in lucid on this machine.

Affects me as well. Lenovo Ideapad U330 w/ BCM4312 running Broadcom STA drivers.

If I run sudo rfkill unblock wifi upon resume, this seems to resolve the issue until the next sleep/wake cycle.

Problem also exists on Dell Inspiron 6400, with Broadcom BCM4401-B0 ethernet controller.
This is with Linux kernel 2.6.35-22-generic (i686)

Sergio Callegari, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 10, 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, could you please provide the information following https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume ? As well, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . However, note you can only test Suspend, not Hibernate, when using a LiveCD. If the issue remains, 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 <BUGNUMBER>

Additionally, if you could try to reproduce this with the upstream mainline kernel that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. 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 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

Please let us know your results. Thanks in advance.
