I installed the 3/15/15 Windows updates, after which my Lenovo Yoga 2-11S lost the ability to connect to our wi-fi router/modem. No other changes were made on the Lenovo. Wi-fi worked just fine on all of our other household devices.
I did a System Restore. Voila! Connectivity returned.
Time consuming, and all I wanted to do at the time was to update Kaspersky. The Lenovo is my secondary computer, used mostly outside the home. I don't boot it up every day, so automatic updates aren't always, well, automatic. Hence, I check for updates before I take it anywhere.
The 3/15/15 update is a very large package. Twenty-two updates (if memory serves), out of which 20 are urgent or important. I'd like to re-install the good updates -- and avoid the one(s) that messed up connectivity.
Is there a known culprit(s) in the 3/15/15 package?
