I too believe this problem is something that started with the last update. I did not notice it before then and it was so bad I have uninstalled all the eyex software and unplugged the unit for now. Sorry I can’t be of more help but I do think it is something in the last update.
One thing to note, and others might want to check, I us Chrome as a browser, and had the eyex extension for Chrome installed but noticed that Chrome was very slow. After removing the plugin Chrome at least returned to normal.
