Any RSSI value lower than -80 dBm is considered poor signal strength. RSSI measures the strength of a radio signal. Use Fast Roaming to speed up security connections when you are using WPA2 Enterprise Security. Use RSSI to ensure that users always experience a strong signal to their Access Point (AP). The 5 GHz signal doesn’t extend as far as a 2.4 GHz, but it has more options to bypass interference problems.When used together Received Signal Strength Indicator (RSSI) and Fast Roaming options help ensure fast, strong Wi-Fi connections. When doing so, look for one that supports both 2.4 and 5 GHz Wi-Fi signals. If your router is older, it might be time to upgrade. If you have plaster walls, consider moving the router as close to the center of the home as possible.

Either your walls are very thick and dense, or your router is old and unable to broadcast very far. If you step a room or two away from the router and find you’re quickly losing the signal, it’s time to consider the age of your router and its placement. Check for interference, consider changing channels, or upgrade to a router that supports 5 GHz (or even 6Ghz) if your current one doesn’t. For instance, if you can reach the edges of your home and still see a 60 dBm signal (or most of the bars), then any issues you’re having aren’t Wi-Fi-strength related.

Once you know how strong your network is, you’ll have a better idea of what to do to improve it. You’ll see dBm measurements in the RSSI entry. Hold the option key and click on the Wi-Fi symbol. On Mac, you don’t need to download any program or app if you want to measure the connected network. Like on a Mac and iPhone, you’ll find dBm measurements listed under the RSSI entry. Just unzip and double-click the EXE file. The program is free, easy to use, and doesn’t require installation. In the past, we recommended NirSoft’s WifiInfoView to inspect Wi-Fi channels, and it also gets the nod for checking Wi-Fi strength.
