I'm a new Fedora user. I'm running Fedora 25 Workstation as the only operating system on a Thinkpad T440p with a Lenovo wireless card based on the Realtek RTL8192EEBT chip. After I suspend, the wireless card will not reconnect. I've tried this command from the answer to a similar question:

su -c 'systemctl restart NetworkManager.service'

... but I still can't re-establish the connection. I'm not afraid to run commands in terminal, but I'm not sure where to start. Does anyone have any pointers for me? Thanks.

Did you you try setting not to turn off the wireless to save energy on the control panel -> Energy and Power settings?

Yes, the wireless card comes back on after Suspend and it seems like it's trying to reconnect, but it never succeeds in reconnecting.

I've been playing around a little more with this issue. I can reproduce the behaviour by turning off the wifi adapter in the Power settings and turning it back on. It seems to get into this loop of trying and failing to connect even if I don't attempt to restart the NetworkManager service. The output from dmesg shows the following chunk repeating over and over
