How to use a Wi-Fi Analyzer App – 3 Super Easy Steps
1. Scan
Most Wi-Fi analyzer apps come with a scan or survey button that scans your surroundings and displays key network details like:
-
SSID
-
Noise
-
Signal Strength
-
Frequency
-
Protocol
2. Analyze
Look over the results and focus on Noise and Signal Strength, both measured in dBm (decibels).
High noise levels deteriorate your network signal strength and result in poor connectivity. Electronic devices like cordless phones, Bluetooth devices, etc., can cause noise.
3. Troubleshoot
Now, it’s not easy to identify and eliminate noise sources. In fact, it’s often simpler to increase signal strength than to decrease it.
Here’s how you can reduce noise:
-
Switch your network frequency band from 2.4 GHz to 5 GHz.
- Both the client devices and APs should be 5 GHz enabled.
-
If you can’t change the frequency band, try switching APs to different channels as part of the 2.4 GHz band.
-
Try to switch off electronic devices around you, and register the noise levels in each instance – A/B test your environment.
-
Try to move the APs around and figure out how specific locations impact the noise levels.
Noise in numbers:
The noise parameter indicates the background noise interfering with your Wi-Fi connection. This figure ranges from 0 dBm (strongest) to -120dBm (weakest). Once this figure crosses -80dBm, your internet speed drastically dips.
And, here’s how you can improve signal strength:
-
Eliminate obstructions around the APs; it is a sure-shot way to improve your signal strength.
-
If your network has multiple keys under a WEP security architecture, reconfigure it to use just one pass.
-
Switch to a different channel.
Signal strength in numbers:
Signals < -40dBm are concerning and < -70 dBm are critical.
If you stand right to an AP, your signal strength is probably -30 dBm: which is the maximum possible strength.
Anything down to -50 dBm is a pretty decent signal strength level.
About Channel Selection:
-
Wireless networks contain channels within a particular wireless spectrum. Sometimes, a channel gets overcrowded which results in decreased bandwidth or connectivity issues.
-
Wi-Fi analyzer tools usually scan through and recommend less-congested channels for your usage.
Final Words
Wi-Fi analyzers have become essential, not just for IT professionals but for anyone seeking a faster, more reliable internet connection. These apps let you monitor network performance, signal strength, channel congestion, and nearby devices. Most provide real-time data on signal quality, interference, and network activity, helping you fine-tune your setup to reduce lag and dropouts.
The Wi-Fi analyzers we reviewed each have their strengths and cater to different needs. NetSpot stands out with its powerful heatmaps and intuitive interface, making it the best choice for home users and small businesses looking to optimize coverage. Wi-Fi Scanner by AccessAgility is another solid option for home users, thanks to its simple layout and handy device-tracking feature. For professionals and small businesses, Wi-Fi Explorer Pro 3 offers customizable scan modes and detailed data. For free solutions, Xirrus Wi-Fi Inspector provides reliable monitoring and rogue AP detection, ideal for smaller setups.
A few extra tips to maximize your home connection: switch to 5 GHz for faster speeds near your router and use 2.4 GHz for wider coverage. For multi-story homes or thick walls, consider extenders or mesh systems to boost reach. Overall, Wi-Fi analyzers make it easy to identify what’s slowing down your network and provide practical ways to improve it.
