0bda:8172 Wireless adapter not working after sleep

[dulbirakan]

I have a USB adapter with realtek chipset (8712u). It gets disabled after computer resumes from a suspend. I can not see any networks listed. I am attaching dmesg output after resume last 93 lines cover the time right before suspend when a connection is established to the time after the resume.

WORKAROUND: Add to /etc/pm/config.d/config :
SUSPEND_MODULES=r8712u

This may be a duplicate of bug 1131914 which I am currently bisecting.

Let me try if it comes back after a while

[dulbirakan (iekanat)]

I suspended and resumed the system, waited 8 minutes and still no wireless. These are the last few lines of dmesg output.

Btw I noticed this is not a problem with my other usb adapter with Realtek 8188cus chipset.

[dulbirakan (iekanat)]

Found a similar problem http://ubuntuforums.org/archive/index.php/t-1745769.html

When I run lsmod both R8712u and R8169 are loaded.

There is a workaround for this problem.

I added

SUSPEND_MODULES=r8712u

to the /etc/pm/config.d/config and that solved the problem.

Hi Christopher,

I updated the bios and tried the wireless adapter. I have not tested it exhaustively but it is not working right. Connection is slow and all. (I ran the codes my bios was F9 and I updated it to F10)

To solve this problem I installed development kernels, various driver packages, blacklisted a few drivers, white listed others and did other stuff which I lost track of and in the current situation I do not think my system is representative of a regular Ubuntu installation.

So I do not think I can provide useful feedback anymore. Also I stopped trying to use the adapter a while back (It took me a few hours to find where I put the adapter actually). I will be installing 13.10 in a few months. I will try the adapter with that and get back.

Best,
db

This still appears to exist with linux-image-3.11.0-13-generic.
Also, I have found an upstream bug that matches this.

[dulbirakan (iekanat)]

Can confirm still having the issue

Hi Christopher,

You asked me this question earlier and I did the update back then and reported back here. Here is the output anyway.

[penalvch (penalvch)]

dulbirakan, could you please test the latest upstream kernel available (not the daily folder, but the one all the way at the bottom) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. 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. For example:
kernel-fixed-upstream-v3.12

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

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

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
