If you have a router, accessing and adjusting its settings is an important way to optimize the connection strength. To start, log into your router's admin page and select the Wireless section in order to adjust certain parameters such as channel selection. This will allow you to choose one of several channels that are less prone to interference from other devices or networks nearby. You can also adjust transmission power levels so that your signal goes further and covers more area; however, this could potentially interfere with other signals if it is set too high. Finally, be sure to save any changes you make before exiting out of the settings menu!
