Larry is having issues on his property where he gets 3G in some areas, and 4G in others. Leo says he's on the edge of both. Will an antenna or amplifier help? Leo says that a cellphone amplifier could help. The benefit being that it becomes a Wi-Fi access point for up to 5 different devices. He can also set up an ad-hoc network with his laptop wired in. A directional antenna aimed at the cell tower will also be beneficial. He should watch his signal as he aims the antenna, and when the signal improves, he'll know where to have it pointed.
