Shankey, thank you for reporting this and helping make Ubuntu better. Could you please connect to ethernet, and execute the following command, as it will automatically gather debugging information, in a terminal:
apport-collect 1506898

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

So here is my whole log of desktop. Please try to figure it out that why its not connecting at all.

[Shankey (shankeybisht3)]

As per your instructions I have successfully updated My BIOS from 1409 to 1801. I have downloaded the BIOS ROM from this link

http://support.asus.com/download.aspx?SLanguage=en&m=M2N68-AM+SE2&os=25

I have also Downloaded BIOS ROM from your Link but it was giving me the following error

"rom id is incompatible with existing bios"

Then i had manually searched and downloaded the correct BIOS and updated My BIOS here is the Output of terminal.

shankey@shankey-System-Product-Name:~$ sudo dmidecode -s bios-version
[sudo] password for shankey:
1801
shankey@shankey-System-Product-Name:~$ sudo dmidecode -s bios-release-date
06/08/2010

Even after the BIOS Update Still WIFI doesn’t work at all. I am unable to connect through my WIFI network/Hotspot. I don’t know what’s wrong.

[penalvch (penalvch)]

Shankey, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, Y, and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

[Shankey (shankeybisht3)]

OK Thanks for your assistance, I am unable to upgrade version to 4.2.4 as its the latest release (According to this link https://www.kernel.org/) is because canonical has not provided x64 bit binary packages. i don’t know why there is no x64bit binary packages but in the Old ones it has. And am waiting for it So here is the below link. Please pass on this message to other can came to know about it.

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2.4-unstable/

Well i have also applied software update as well as security update (there was also new update of network manager) to my PC after that my wifi works!!!...But signal strength remains too low..but when i turned off and after sometime turned on MY desktop. Same thing happened WIFI Shows but it doesn’t connect to any network . My internet became unusable again.

I will upgrade to the kernel as soon as possible and ill let u know about That as well as its results.

[Shankey (shankeybisht3)]

Ok so I have upgraded my kernel to 4.3-rc7. But when Ubuntu boots fully It doesn’t detects my wifi card at all. There is no wifi at the network manager and then i have recompiled the package through this link "https://github.com/lwfinger/rtl8188eu" rebooted and after wifi detected. when i connect it to my networks its having the same issue. its keep on showing connecting status but never connected. And also its signal strength is too low even in 4.3 rc7 kernel. Still wifi is unstable/un-usable.

[penalvch (penalvch)]

Shankey, could you please plug the device in, unplug as many others as possible, and before installing the driver from github, please execute the following command and post the results:
usb-devices

[Shankey (shankeybisht3)]

I have unplugged it but same problem. and here is the output of my usb-devices

[penalvch (penalvch)]

Shankey, the issue you are reporting is an upstream one. Could you please report this problem following the instructions verbatim at https://wiki.ubuntu.com/Bugs/Upstream/kernel to the appropriate venue (TO: Greg Kroah-Hartman and Larry Finger, CC: driverdev-devel )?

Please provide a direct URL to your newly made report when it becomes available so that it may be tracked.

Thank you for your understanding.

[Shankey (shankeybisht3)]

OK and should i post the output of usb-devices of Mainline kernel??

[penalvch (penalvch)]

Shankey, the only part that was of interest is the few lines regarding your WiFi device.

[Shankey (shankeybisht3)]

In this Link "https://wiki.ubuntu.com/Bugs/Upstream/kernel" mailing list part is not fully understood to me. So how can i send the mail to kernel team??
