Purchased Doser 2.1 standalone Install is a problem all weekend...

GHL is now blinking yellow.. over the weekend here is the final result.. I spent the weekend .. installing, deleting and reinstalling all the software.. to those of you that have windows 7 you will have an issue upgrading the firmware. My issue.
GHL unit does not work with either my windows 7 or windows 10 computers. I can control it through them with the GHL control center software program ONLY to the extent through the USB.. when i try to control it through the pc without the usb attached and through the LAN or WIFI i can control the stirrer but not the doser pumps.. I get a return of ERROR 50 or ERROR 28 .

My static ip address is good. I pinged it and it came back. I see it in the router so that is good. WIFI was constantly dropping out of the unit. it would lose the signal even though only 50 feet away and other wifi devices in the room had full signal.

Help please..

Also., uniti is blinking Yellow not solid Blue
