Wi-Fi problems can be frustrating. Slow downloads, buffering of videos or calling for calls often indicate a weak signal strength. The good news is that Windows, Mac, Android and iPhone all offer ways to check your Wi-Fi connection. Once you know how strong or weak the signal is, it is easier to solve cover problems.
Check the WiFi signal strength for a rapid estimate.
The easiest way to check your WiFi power is by looking at the signal bars. On Windows and MacThe Wi-Fi icon in the taskbar or menu bar shows signal levels from one beam (poorly) to full rods (excellent). On Android and iPhoneThe status bar shows a similar icon.
This method offers a fast snapshot, but it is not completely accurate. Bars do not tell you the true signal measurement in DBM and they can vary between devices. For a more precise reading you must use built -in tools or apps.
How to check Wi-Fi signal strength on Windows
Windows offers different ways to check the signal strength.
- Open Institutions From the start menu.
- Go to Network and Internet> Wi-Fi.
- Select your connected Wi-Fi network to see the strength.
For more information you can use order prompt:
- Type CMD In the search bar and open assignment prompt.
- Enter
netsh wlan show interfaces. - Search for the Signal Veld, that shows power as a percentage.
Advanced users can also RSSI value (Received signal strength -indicator), measured in dbm.
How to check Wi-Fi signal strength on Mac
Mac computers contain a built-in way to view detailed Wi-Fi statistics, but it is not immediately clear. Apple hides this function behind a simple shortcut that reveals more information about your current wireless connection.
To use it, press and hold the Optional key Click on your keyboard and then click on the WiFi icon In the menu bar at the top of the screen. This promotion unlocks a drop -down menu that goes beyond the usual network list. Instead of just showing which network you are connected to, it shows technical details about the connection.
One of the most important values shown is:
- RSSIthat measures the signal strength in DBM.
- NoiseThat background interference represents that influences your connection.
- ChannelThe frequency channel that your router currently uses.
The RSSI number is the most important metric to concentrate on. Unlike WiFi bars, who only give a rough idea, RSSI is exactly. A lecture close to -30 dbm Indicates a very strong signal and almost perfect conditions. A number around -50 dbm Is still excellent for streaming or video calls. As soon as the value drops to -67 dbmThe performance can start to delay and at -70 dbm or worseThe connection becomes weak and unreliable.
How to check Wi-Fi signal strength on Android
Most Android devices display signal strength in Wi-Fi settings. Open Settings> Network and Internet> Wi-FiTap your connected network and you will see its power as bad, honest, good or excellent.
For more accuracy you can install Wi-Fi apps that show DBM lectures:
- Wi-Fi Analyzer
- Netspot for Android
- Open signal
- Network signal information
- Speed test by also LA (test speed instead of DBM but still useful)
These apps provide clearer measurements than the standard settings screen.
How to check Wi-Fi signal strength on iPhone
Go on the iPhone, go to Settings> Wi-FiThen tap the name of your network. The page Details shows basic information but not DBM -strength.
For advanced measurements, install Apple’s Airport utility App Store app. After you have enabled Wi-Fi scanning in the app settings, you can perform scans that display RSSI values in DBM for all nearby networks.
Use Wi-Fi Analyzer Tools and Apps
If you want a deeper view of your WiFi environment, third-party tools are the best option. These apps not only measure your signal, but also card coverage areas and detect interference. Popular options include:
- Speed test by also LA – Fast performance control.
- Mains – Windows and Mac software with heatmaps.
- Wi-Fi Analyzer (Android) – Shows signal strength in real time.
- Airport Utility (iOS) – Scans and reports DBM values.
- Acrylic Wi-Fi (Windows) – Advanced analyzer for networks.
- Ekahau Hittemapper – Professional mapping for large areas.
These tools are especially useful for companies or large houses with many devices.
Understand signal strength measurements
WiFi strength is usually measured in DBM (decibels compared to a milliwatt). The closer the number is too zero, the better the signal.
- -30 dbm – Excellent
- -50 dbm – very good
- -67 dbm – good enough to stream
- -70 dbm – weak, calling calls
- -90 dbm – Unusable
Bars are easy to understand, but DBM values are more reliable for solving problems.
What to do if your WiFi signal is weak
If your WiFi signal is consistently weak, there are different fixes that you can try:
- Come closer to your router or put the router in a central location again.
- Reduce obstacles such as thick walls, metal furniture or appliances.
- Start your router again to renew the connection.
- Shift between 2.4 GHZ (better reach) and 5 GHz (Higher speed, shorter range).
- Add one WiFi-Extender or MESH system To cover dead zones.
- Work the firmware of your router or replace old hardware.
- Contact your internet provider if the problem continues.
These steps can significantly improve coverage and stability.
Conclusion
Checking your WiFi signal strength is easy on any device. A quick glance at the WiFi bars gives a rough idea, while built-in tools and apps offer precise DBM measurements. Insight into your signal strength helps to identify whether slow internet is caused by poor coverage or another problem. And if your WiFi is weak, simple adjustments such as repositioning the router or adding an extender often solves the problem.
