168c:0034 [Acer Aspire V3-551] Wireless dies out constantly on 13.10

[RedMirtle]

The wifi disconnects constantly. It can take an hour or five minutes. I originally used the normal Network Manager, case in which the connection i was connecting to would actually disappear from the list until i requested the Network to be disabled and enabled again. I changed to Wicd, following a suggestion in another report and the disappearance of the connection was fixed, though it would still disconnect.
Everytime the connection is about to drop, the computer laggs.
This problem began during Kernel 3.5. I used to boot to that in order to avoid it and the wifi worked flawelessly. Unfortunately with Salamander, that Kernel doesn't start the graphics properly (I get a funky X instead of a mouse pointer). After 3.5, I tried every kernel that was out as they were periodically updated, until 3.11, to no avail.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 kernel[0].

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'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hey, I asked in private if I could make the system boot beyond the graphic card crashing at boot-up. In the meantime I'm unable to test the 3.12 kernel, system boots but not the graphic environment, i just get the X instead of the mouse pointer and all black.

[Joseph Salisbury (jsalisbury)]

Thanks for testing the latest mainline kernel. Can you also test the latest upstream 3.11 stable kernel:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11.7-saucy/

[RedMirtle (faceman8)]

No Graphic Card for 3.11 either

[Joseph Salisbury (jsalisbury)]

Can you follow the "Boot options" instructions on the following wiki to enable additional output on boot:

https://wiki.ubuntu.com/DebuggingKernelBoot

As mentioned on the wiki, it would be great if you can attach a log file which may have captured any messages you see. If you are unable to capture a log file, a digital photo will work just as well. As a last resort you can even copy messages down by hand.

RedMirtle, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please just make a comment to this.

If reproducible in Trusty, could you please test the latest upstream kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc2-trusty/ and advise to the results?
