Wifi Connection Question

Hi, I just got my Six robot and assembled it. I can't get it to connect to my PC. I've been through the tutorials. Here's the basic info:

EZ-B v4 0684 is showing up in my list of available networks. I can connect to it but there's an exclamation point over the signal strength icon.

I've been through the tutorial and have followed the instructions. When I click on "Connect: in the Connection window I get the message "Could not connect to the EZ-B"

I see from other comments that there are issues with Avast, HP's etc. I don't have these variables.

Any help would be appreciated.
