Win 8.1 Install Problem

Prior to downloading 8.1, my laptop was up to date with drivers and such. Not problems at all to include wireless connection. I just downloaded 8.1 from the store. During the install/setup once I got to wireless connection, no matter which of my two connection I tried to connect to I couldn't. So, that is as far as the setup would allow me to go. Not sure what the deal is so any suggestions are welcome. Thanks

Laptop: Dell XPS 12 9Q33

Try updating your driver from here:

Like I said, all drivers are updated. It's a 2 week old system and one of the first things I did was ensure drivers were updated.
