@Francoisgs Was an issue for me to get it connected but I used the WPS option in the app and it connected, then I turned off the mesh option for the canon printer once it was connected.

  @Alexmesh thank you very much, would you mind giving me a little more detail  ( am no IT genius ;)   )thanks a million.

Presently on my printer, I can see it is connected to wifi but it seems an issue of recognition between Canon and Apple as with a Microsoft computer it works. The first 8 days I set up my new printer it work like a clock beautifully but after the eight-day no more connection and was wondering if Deco mesh could be an issue??? so frustrating :(  thanks a million once again, Francois
