Usually a kernel/driver issue, but lets start with kde-plasma-nm
IMHO, this is clearly either a driver issue or an external problem (hardware issue, issue with the access point, interference, …).
(In reply to Kevin Kofler from comment #3) > IMHO, this is clearly either a driver issue or an external problem (hardware > issue, issue with the access point, interference, …). I don't think its a access point issue, since it happens always on all wireless access points. - Kiril
I have the same basic issue. However, it doesn't always say it has disconnected, it just stops working. Hasn't worked properly since kernel 3.12.x. Currently using 3.14.2 on KDE and F20. Intel Corporation Wireless 7260 (rev 6b).
FYI currently running 3.12.10-300.fc20.x86_64 and it works perfectly. Same access point, same setup.
The suggestion here fixed the problem for me: https://bugzilla.redhat.com/show_bug.cgi?id=1087717
Kernel and firmware updated today and unfixed it. Had to perform the same fix again. Surprise surprise...
Same problem with both kernels 3.14.9 and 3.15.2 (problem persists since I got my Lenovo 440s with intel 7260N a month ago). After a while, specially if wifi is not used for a while the connection stop working. NM thinks that it is still active but the connection does not work. Tried all the firmwares -7, -8, and -9. This problem is widely reported on the web, including for Windows. I tried all suggested solutions, turn HT mode off, turn blutooth off, disable powersave mode to no avail. This is not a Fedora problem but it seems like a concerted effort is needed to at least find a way to "mask" the problem.
Here is the iwlwifi crash messages in /var/log .

I also have this bug. It's very annoying.
This bug has dissapeared for me since a few days
It is still there with 3.15.10-201 in F20. Very annoying. Perhaps the kernel 3.16 will have some improvements.
Intel has put out new firmware for 3.14+ kernels: 25.222.9.0.... hopefully it makes it into firmware package soon.
Kernel just updated to 3.16.2-200 and the wireless interface disappeared altogether. If I boot any older kernel it works fine. Please fix.
Kernel updated and all seems well. Firmware package updated also and so far no problems.
But unfortunately the firmware update did not update to the latest 7260 firmware 25.222.9.0. Looking at the branches perhaps kernel 3.17 with the latest firmware will solve the drop problem.
Kernel 3.16.6, latest firmware 25.222.9.0 kernel messages and dropped connections.

This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
