j6400 series printer stopped wifi printing

HP Recommended
hp j6400 series printer
Microsoft Windows 10 (64-bit)

I have a hp j6400 printer that has served me very well over the years.  Recently, I find that I cannot print wifi.  I can print by connecting directly by USB.  I have run the Print and Scan Doctor several times.  Now when asked which printer, I have the following choices.  hp office jet 6400 series _TMP00 USB, hp office jet 6400 series  IP, HP400BCD( hp office jet 6400 series) IP  These are all "installed".  I have always used the hp office jet 6400 series  IP The HP doctor states "failure to communicate".  The doctor found and fixed HP400BCD, but this does not appear in my selections in HP solution center. I have powered down the printer and router for over one minute each, but this did not correct the issue.  I am using Windows 10 with latest updates on a Dell Inspiron 5567.  Sorry for the long diatribe, but wanted to give all info I can.
