Problem printing with MG 5420 via wireless

[mellodar]

I have been attempting to print for sometime.  Have had the Canon MG5420 for several months and it worked great until today.  All of my computers are unable to "find printing device."  Have completed advanced wireless setup several times with password.  Printer confirms it has connected each time.  I have turned the printer off to reset, still is unable to be found by my computers and iphone.  Completed a printing of the Network Configuration Page and it shows that signal strength is at 96%.  Suggestions on where I go from here?

Thanks.....
