However, if you spot a Wi-Fi signal listed at -90, the service is so weak you probably can’t connect to that network. If you see -30, you have a “perfect connection,” and likely, are standing next to the Wi-Fi router. The first thing to know is measurements of dBm will display in negative numbers. Keep track of how far you are from the router, and how many walls there are between it and you. If you’ve determined your Wi-Fi connection is weak in a particular spot, the next thing to do is walk around and pay attention to the Wi-Fi bars on your smartphone or tablet. If you have similar results with both, you have an excellent baseline to use. Compare internet performance on both devices and see what they display for Wi-Fi strength. If you checked a phone, consider testing a tablet, too. But it’s worth consulting a second, or even third device. Usually, four or five curved lines make up the Wi-Fi symbol, and the more that are filled, the stronger the connection.Įvery phone, tablet, and laptop is different and may indicate a different Wi-Fi strength. Whether it’s using an iPhone, iPad, Android, Mac, or Windows PC, you should have a Wi-Fi connection indicator. To check the strength of your Wi-Fi, the first thing to do is look at the device having issues. Checking Wi-Fi Signal Strength the Easy Way If the ethernet connection is fine and a router reset didn’t help, then it’s time to check signal strength. If you still have issues, the network is the problem. Try using the internet with a device connected through ethernet. If the problem persists, the next step is to check if Wi-Fi is the problem. If the internet on your computer or phone seems slow, start by rebooting your router if you have access to it. Not every connection problem is a result of weak signal strength.
