The only reason I suggested disabling the anti-virus program is because most of them have a firewall component that blocks the network traffic from the tablet to the companion. For users who know how to ensure that the network traffic is allowed through, they obviously don't need to disable the anti-virus side of things - they just have to either add forwarding rules or disable the firewall component.

Can you tell me what versions of both the companion and the tablet software you are running? The latest versions of each are v1.3.0 and 2.2.2. You should make sure you have both up-to-date.
