AT THE START
Your table must communicate with the control program (on the PC) at the start. The green wifi icon in the header shows that there is communication. You need to find out why there is no communication if the icon would not be green.
Red = No network selected. Go to Settings/Network and set tablet to the same network as the PC (see BT Admin to find out).
Orange = BT Admin not found. Check that it is running.
Also check that the Hardware id is a 5 digit no. Reset it as described in the Low ID doc if it would be a low number.
Green wifi icon = Resume should work
Orange = BridgeTab Admin not found. Check that it is running.
Red with ? mark = incorrect network. Set it back to the network used at first start. i.e. the same as the PC uses.
Red (crossed over) = No network found. Check that the router is up and running.
