Hi all. We know that one of the main problems for those who use wifi modem is weak Wi - Fi signal. Signals tend to weaken as one moves away from the antenna, this coupled with the potential barrier (walls, doors, other antennas, etc.) reduce the scope that can have our modem. The far away we go from the modem antenna the less signals we get and hence we face problem surfing Internet. How to Increase WiFi Signals with a CAN Fortunately for those who are curious about these questions, there is a very simple and practical trick that can increase the WiFi signal with a can of beer, soda or a drink that comes in a similar package. To do this, we need only an empty can (plastic), scissors, knife and duct tape. The process is as simple as you can see in the image.
