WiFi "flickers" on and off

asked 2017-04-15 18:22:11 -0500

A few days ago my Wifi began to switch on and off about every 3 seconds. The icon in the upper right corner switches between the Wifi symbol, a question mark, and the three dot symbols. My local internet has been acting up, but we use several other devices without trouble. I tried re-installing network manager, but the problem persists. Today I had to put my computer in airplane mode, when I turned it back on it did not detect any networks. I searched online and fixed it by following gavtalor's answer to question 97160. My computer now connects to my network, but it still switches on and off. Does anyone have an idea of what could be causing this?

I have fedora 20.

I have almost the same problem on Fedora 25. When I log in, airplane mode flickers on and off multiple times. At some point, it stops flickering and airplane mode stays enabled, after which I have to manually disable airplane mode. By the way, my laptop has a airplane mode button on the keyboard. This only happens on Gnome (not on KDE).

If you really use Fedora 25, as you wrote above, then please update to a more recent version, preferably Fedora 25. Fedora 20 is out of support for about two years. Asking or answering any questions for unsupported versions is a waste of time, the situation might be completely different now.

The issue you are describing sounds like a driver issue. Please make sure you are using the latest Linux kernel (that is 4.10.9 at the time I'm writing this), which can be installed in Fedora 24 and later by updating your software. Probably the Wifi device is too new to be supported by your outdated software.

In case an update does not fix your problem, there are plenty of guides on the internet, e.g
