canon mg3250 wireless

my printer used to work fine on my bt hub 5 , nothing has changed but it now wont connect , printer works fine with usb lead , tried re pairing wps but wont connect , downloaded canon software and when I get to the select access point it shows my network but the connect button is greyed out so i cant select it , all the other networks that it finds are greyed out as well , the only one that isnt is our neighbours podpoint which is an electric car charging unit !!!! , Bloody stupid printer

 

I had same problem with my canon mg 3250.....scoured the net tying to find cure tried few ideas but problem came back next time I switched printer back on....eventually went and bought it's successor and much
better networking and general functionality £50 if I remember rightly with fair amount of free ink provided for a change.
net was full of people experiencing similar problems.
