A wireless channel scanner will be of great help in seeing which WiFi channels are mostly used by the neighboring WiFi networks. By choosing the least crowded wireless channels for your network to operate on, you can get a much better and consistent WiFi connection. A WiFi channel analyzer collects the information about all nearby wireless networks, and this information includes the channels those networks operate on.

By putting these networks channels on the graph a WiFi channel analyzer will make it easy for you to see the channel overlap.

Here are our top choices of the WiFi channel scanners ranked after their user-friendliness, features, and reliability:. NetSpot is a fast wireless network scanner with comprehensive survey features. NetSpot's free Discover mode can instantly detect all wireless networks around you listing the channel each network operates on. By putting both 2. Its straightforward user interface makes it easy even for complete beginners to discover which channels are used the most and which are used the least.

Get NetSpot. Most of them have a hardware inside that automatically selects the proper WiFi channel and adjusts the output power thus boosting throughput and cutting down the interference. Using the 5GHz band and having decently thick walls as well as the general lacking of 5GHz devices usually means that there is a very little interference in your space.
