How To Do A WiFi Survey On Windows

Conducting a WiFi survey on a Windows computer can be an invaluable step in assessing wireless network coverage, signal strength, and identifying areas that may benefit from a network upgrade. In this how-to article, I’ll walk you through several methods I’ve used to perform a detailed WiFi survey, using built-in Windows tools and third-party software, ensuring that your survey captures all the necessary data for optimal network performance. We’ll also explore how to interpret the survey results and implement improvements.

Navigating Dead Zones 📶

• Experiencing poor WiFi connectivity in certain areas of your office or home can be frustrating. Dead zones are often caused by physical obstructions or interference from other devices.
• Determining the exact location where signal drops or is weak is crucial for resolving these issues.
• A WiFi survey is an effective approach to systematically map out the signal strength across different locations.

Network Planning and Expansion 🌐

• When looking to expand your WiFi network, precise planning is key to avoid overlap and excessive expenditure.
• Performing a WiFi survey allows you to identify the areas that require additional coverage.
• A WiFi survey is critical for determining the optimal placement for new access points.

Improving Network Performance 🚀

• Networks can suffer from interference due to the presence of other wireless networks nearby.
• Channel overcrowding and interference can significantly hamper WiFi performance.
• A WiFi survey helps identify the least congested channels and optimal settings for your network equipment.

Mapping Your Survey 🗺

• For accurate results, create a floor plan and mark the locations where you check for WiFi strength.
• Use a heat mapping tool within WiFi survey software to visualize signal coverage and plan access point placement.
• While performing your survey, be sure to test in various conditions, including different times of the day and locations where devices are commonly used.

Understand the Interference 📡

• Other devices such as microwaves, cordless phones, or Bluetooth devices could affect your WiFi signal. Ensure you account for these during the survey.
• Investigate potential channel interference from neighboring WiFi networks and consider changing your router’s channel to a less congested one.
• Walls and large metal objects can be significant signal barriers; consider these when reviewing your WiFi survey data.

Ensuring Accurate Readings 📐

• Take multiple readings at each location to ensure accuracy.
• Be aware of WiFi ‘halo’ effect – the phenomenon where signal strength can be stronger a few feet away from the source than directly next to it.
• Be familiar with interpreting signal strength metrics, like RSSI (Received Signal Strength Indicator) and dBm values, to make informed decisions.

Once you’ve gathered enough data from your WiFi survey, it’s time to enhance your network. Start by adjusting the placement of your routers and access points. In many cases, moving these devices away from obstructions and to central locations can significantly increase coverage.

Consider upgrading hardware if necessary, especially if you’re using older technology. Modern routers with multi-band support can diminish interference significantly by providing additional frequency bands for devices to connect.

You may also want to delve into advanced settings like Quality of Service (QoS) to prioritize traffic, or implementing MU-MIMO (Multi-User, Multiple-Input, Multiple-Output) technology if your hardware supports it, to better manage multiple connections.
