I have a 3100cn and I have it hardwired to my main PC for printing.  However, I also have another PC for my grandchildren's use connected through a Linksys router and would like to hook it up wireless to the 3100cn printer. 

 

If my memory serves me correctly, this used to work, but I have changed out to a newer system for the grandkids. 

 

Please advise what I need to do to have the grankid's PC connect to the 3100cn.  Your assistance is greatly appreciated.  I am not a novice, but also not an expert like so many of you.
