Pxma MG6821 will not connect in WIndows 10

[SlowJoeCrow]

I'm having major frustration here, my  MG6821 MFP shows as disconnected in WIndows after the last WIndows Update  when using a WSD port. The printer is definitely online and the scanner utility sees it no problem and I can open the printer's web page using it's IP address but I cannot get the driver install tool to discover the printer port and the printer will only work with WSD and cannot be installed by IP address. Windows firewall is disabled, the WAP does not have device isolation enabled or internal firewall so what gives?

Thanks for the fix, I still had to set up by USB but it's printing again.
Peeve mode on, WSD that has to be detected can be a major PITA to set up compared to old fashioned LPR or Jet Direct where you just punch in the IP address. I've also seen performance differences on Ricoh MFP machines where WSD was noticeably slower than direct to the printer's IP.
