Hi there,

When I resume my laptop from suspend the wifi settings state that the hardware is disabled. I have a ThinkPad E540 with an Intel 7260 wifi card. Cycling suspend a few times resolves this. I am running Fedora 22.

Relevant output from lspci:

05:00.0 Network controller: Intel Corporation Wireless 7260 (rev 83)

Does anyone know the root of this problem, or does anyone have suggestions on where to start looking for the issue?

This worked for me on Fedora 24, on a Dell E7450 with Intel Wireless 7265:

echo '#!/bin/sh
case "${1}" in
    ( sleep 3; nmcli r wifi on ) &
' | sudo tee /etc/pm/sleep.d/10_resume_wifi

Note that you should first check that the command nmcli r wifi on reactivates your wifi (usually this is the case if gnome-shell 3.20+ displays the airplane icon). In my case I had to add sleep 3, probably because of a race condition: the hardware is not recognized yet when post-resume scripts are executed.

I have the same thing on a dell latitude E7250, fedora 22 as well and this wifi hardware:

02:00.0 Network controller: Intel Corporation Wireless 7265 (rev 48)

It does not happen all the time. When it does, to get the wifi working again I have two options:

  • in a shell, enter:

    nmcli radio wifi on

  • a keyboard shortcut: Fn+ the radio blue icon (in this laptop that is the PrtScr key).

Either way the wifi radio gets enabled and I can go on after suspension.

I have just set up a Dell Latitude E7450 running Fedora 22 and am experiencing similar behavior.

Installed Packages NetworkManager.x86_64 1:1.0.6-8.fc22 @updates

Linux hostname 4.2.8-200.fc22.x86_64+debug #1 SMP Tue Dec 15 16:31:26 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

1) The command, nmcli radio wifi on, does not seem to turn the hardware on. 2) No hardware switch on this laptop 3) The Fn-PrtScr toggles "Airplane Mode", Not "Hardware WiFi On/Off" 4) Going in and out of Suspend has worked in the past...but appears not to be reliable at all. 5) I have tried rfkill unblock does not work either

Any thoughts?

This is a basic answer from my experience with Lenovo units and bluetooth/wifi. Try pressing the blue function [Fn] key (at the lower left corner of your keyboard) and the the blue antenna key usually with the Function keys. Let me know what happens. Hope this helps.

I don't have a blue fn key, it's a thinkpad with the new keyboard type. Besides that - fn+radio button just toggles wifi with NetworkManager. I took a look at rfkill, it states that it is hard blocked. Yet there is no physical switch.
