There are a few things you can do to try and boost your RV WiFi signal. First, make sure that your router is in a central location within your RV. If it's off to the side or in a corner, it may not be able to reach all areas of your RV evenly. Second, try moving any metal objects away from your router. Metal can interfere with the signal and cause dead spots. Finally, consider investing in a WiFi range extender. This can help extend the reach of your signal and eliminate any dead spots in your RV.
