Thanks for the update, matthew114. I have an HP, so DELL support is not going to help me. It would be nice to know what they did to fix your problem.
I figured that 16.x is the version of ProSet Wireless Intel software, which installs 15.10.3.2 wireless driver. I also bought a lower-end HP with Qualcomm wireless card and that one doesn't have any problems.
What's the guidance from Intel here?
Thanks,
Alec
