Sorry for the late reply. I installed the kernel-firmware package from
kernel-stable repo (provider obs://build.opensuse.org/Kernel)

zypper info says kernel-firmware is version is 20150715it-35.1 and
kernel-desktop is reported 4.1.2-1.1.g5ccacb4, both from the same provider.

WiFi is working (I'm posting this running these kernel and firmware packages) 
So your diagnostic was spot on. Thanks again for your support.

Are you're planning to somehow package together the latest kernel and firmware
packages? Otherwise people with old kernels upgrading to the next OpenSUSE
release could also run into this problem.
