Hi Joe,
I don't have any of these events on the old driver version (15.5.6.48) that I'm using. But on Saturday I had upgraded to the latest drivers (15.12.0.6) and had a really bad time - worse than normal. Absolutely would not connect after all the tricks. I now see in the event log several 5055s and 5007s. I will send you the saved events .evtx file in a private message. I believe that was a different kind of bug than the one I'm getting while on 15.5.6.48.

I have yet to confirm this, but while on 15.5.6.48, I'm pretty sure I can still access devices on my local network. Like, I think I can print to my Apple Airport-connected printer! But the other computers/devices don't seem to be affected at those times. And as I mentioned, I seem to experience this on other WiFi networks at different locations and different access point hardware. In those cases, I am also close to the access point so interference is not an issue.
Thanks!
