I tried disabling PMF, to no avail.
Comment 4 Laura Abbott 2018-09-13 16:15:00 UTC 
F28 has been rebased to 4.18. Can you test on that kernel?
Comment 5 John W. Linville 2018-09-13 17:53:07 UTC 
Have you tried booting with selinux disabled (i.e. "selinux=0" on the kernel command line)?
Comment 6 Wayne Walker 2018-09-13 19:03:14 UTC 
getenforce shows 0, so selinux is disabled.

I just did a dnf update, rebooted into 4.18.5, and now it works for 3 out of the 4 SSIDs.  Doesn't connect to one of the 2.4 GHz SSIDs.  Good enough for me.

Thanks for letting us know.
