RBR750 Slow Upload Speed

Please help!!

For whatever reason within the last week, I have lost all of my upload speed.  Prior to this taking place, I was consistenly receiving more than 50mbps and recently it has been ranging between 0.05 and 2.5 mbps.  My download speed has been excellent and consistently topping out north of 500 mbps.  Both my wife and I work from home and this is only going to get worse. Details below on what I am using.  Yesterday I did a manual update on the app for FW v.3.2.16.22 and for whatever reason the speedtest on the app is not showing a connecting either.  Upon calling Wow, they indicated that the numbers looked good on their end and that because I have my own router, there is nothing they could test against.  What a mess.
