There are not many options if the connection is weak. The only option is to try to change the location of the unit inside the object (boat, house) and its position in relation to the floor - vertical, horizontal, perpendicular. Note, when you change location/position the unit might not pick up the network immediately. The maximum power that the mobile module gives is when it starts operating - i.e. at the moment when you power on the device. So the best way to check a new place for the unit is to switch the power off and power it on again and wait to see if it is able to log onto the network. Then send the command “STATUS” and compare the signal report in the new location/position of the unit.
