One specific laptop will not connect to our Xfinity Wifi Extender

I just recently installed an Xfinity Wifi Extender in my home office.  I have two laptops that I use here, one for the office and one for personal.  The personal laptop connects to the wifi extender and the work laptop absolutely will not connect to the extender.  I have forgot network and tried to rejoin it.  I have turned off wifi completely and tried to rejoin.  I have both laptops sitting next to one another on my desk next to the extender.  

Any suggestions would be appreciated!
