Initially reported to opensuse: https://bugzilla.novell.com/show_bug.cgi?id=852887 Occasionally when this latop wakes up the wifi interface will be down, and unable to be restarted unless I unload/reload the driver module. The interface is an RTL8191SEvB, supported by module rtl8192se. The issue is not readily reproducable. It's really only a minor nuisance, but it was suggested to me on opensuse-factory that I ought to report it.
I also get this with the RTL8191SEvB. It happens about 1 out of 10-15 times I resume from sleep. I find it more than a "minor nuisance" as have never been able to recover my system from it. Trying Per Jessen's suggestion of unloading/reloading the driver module causes my system to hang ("modprobe -r rtl8192se" followed by "modprobe rtl8192se" -- is that what you were doing Per?). It usually works again after restarting my system but sometimes the only way of getting it back is to power off completely and pull out the battery. My system: Toshiba Satellite A660 OpenSUSE Leap 42.2 KDE Linux 4.4.36-8

I most likely did "rmmod rtl8192se" then "modprobe rtl8192se". I have not had this problem for quite a while. My system: Toshiba Satellite L670, openSUSE 12.3, kernel 3.11.10.
