Slow wifi after update

I noticed after I downloaded the newest update that my wifi is alot slower at home. Everything else I run from home (ps4, computer,etc) run fine. Anyone else running into this issue? I just got a new modem/router from Comcast and internet was fine before I did this update. This is a dual band router which I thought may have something to do with it but not sure. Anyone else having issues?
