Just bought a Mofi4500 and in the process of getting it setup. Maybe a dumb question but which side of the Mofi is the front? When aiming the router towards where a cell tower is located (can't literally see the tower)....which side of the Mofi4500 do I point towards the cell tower? or does it matter? My area doesn't have that many true cell towers...some are just power poles with a device mounted on the pole. I can aim the Mofi in a certain direction and get a certain download speed (connected to my laptop) and then turn the router 180 degrees and sometimes get a similar download number. Trying to determine which direction the signal is coming from.............thanks!!!
