A hidden feature of Windows 10
Well, this morning I decided to prepare for next month's ski trip by checking out my laptop. Good thing I did! It couldn't connect to the internet. How baroque is that? So I turned to the desktop and Googled the problem. It seems to be a known feature of Windows 10, which I installed a few weeks ago, luckily within the 30-day rollback period. Now I'm running Windows 7 again -- and connected to the internet. Glad I didn't discover this feature in the airport!
