Read the text and answer the questions. Wireless Controller Complications

Wireless video game controllers can sometimes be problematic, but in most cases there is an easy fix. One very common issue is that the controller will not stay connected. To resolve this problem, move closer to your gaming equipment. It also helps to move other nearby wireless devices, so that they do not interfere with your wireless signal. Sometimes the controller may lose connection because it simply does not have enough power. This dilemma can easily be solved by charging or replacing the batteries. If your wireless game controller is not acting properly, move closer, clear away other devices, and make sure it is properly charged.
