There are a few things you can do to try and boost your Mediacom WiFi signal. First, make sure that your router is in a central location and not blocked by any walls or obstructions. You can also try moving your router to a higher spot, such as on a shelf or table. If you have a lot of devices connected to your WiFi network, it can also help to disconnect some of them to free up bandwidth. Finally, you can try restarting your router or modem to see if that helps improve your signal strength.
