So are you connected direct off your modem? Are you using a VPN to connect to your business network?
In my Deco App there are multiple "AntiVirus" settings: You could try toggling those on/off and see if that allows you to connect to your business network. There was an update at the beginning of April - did you install that?
Well...I can’t get this thing to play with my work’s VPN. Unless I somehow get this figured out, I may as well have just burned a couple hundred bucks.
