To go with WiFi speed test, download Free NetSpot, open the app and start a new site survey. When you get to the Active Scanning screen, simply select the particular wireless network you wish to test the speed of. Keep in mind that you can only run an active scan on a network you have access to (either an open network, or one that you have a WiFi password for saved on your laptop).
With this option selected, NetSpot will measure wireless network speed at each data sampling point by sending queries to random servers and calculating the time it takes for them to be sent and received. Repeat this process with each network you need to test. Once you complete the survey, it's time to review your WiFi speed visualization data.
Troubleshooting Your Wireless Speed
When your survey is complete, you will be able to view heatmap visualizations of your survey area for upload speed, download speed and wireless transmit speed. The heatmaps will highlight areas of the best and worst WLAN speed. Once you have identified problem areas, you can then start to troubleshoot the cause of the poor WiFi speed. Some questions to ask:
- Could slower APs be overpowering faster ones?
- Are your APs overloaded, with too many trying to access the network at one time?
- Are you using the best 802.11 protocols and bandwidth for your particular situation?
- Are your wireless adapters overloaded or outdated?
- Do you use wireless extenders or repeaters?
- Could signal interference be causing problems?
Once you've got your network running the way you want it, the next challenge is to keep it that way. NetSpot can help you monitor it. Just perform a scan once a month or so and spot wireless network speed changes before they become problems. Visit NetSpot knowledgebase to learn more.
