My printer finds my lan id but it does not prompt me for the network password when I try to access my network.  I have searched this forum for the above title and found a solution to this problem which says to disable the 802.11r wifi property.  I tried to set the security to my lan adapter to none but it will not let me do that.  How do I get my Canon Printer Pixima MG6620 to prompt for the password for my network?
