Lenovo Thinkpad Carbon X1 2015 Wireless issue

[XicoSM]

I have recently bought a Lenovo Thinkpad Carbon X1 2015, the third generation, which also has an Intel 7265 card and also found problems with it.

I'm using the latest ubuntu, Vivid, and the card works fine when the laptop is started, but once it disconnects from a network, due to poor signal in my case, it cannot reconnect it back until I do a full restart of the laptop.

Even if I click on disable network and re-enable later, it does not show any wireless networks to connect to.

XicoSM, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test 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 bug 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 XY and Z are numbers corresponding to the kernel version.

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

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