This Wi-Fi network discovery tool shows all wireless hotspots’ MAC address, encryption, signal strength and channel, and is the default troubleshooting tool for millions of Wi-Fi users worldwide.

Measure Wi-Fi signal strength

inSSIDer for Home helps you measure the signal strength and estimate the performance of Wi-Fi in different locations. See how walls, stairs and doors affect your wireless network coverage.

Choose a better channel for Wi-Fi

All Wi-Fi must share channels with other networks in the environment. Too many networks sharing or overlapping a channel can degrade the performance of all Wi-Fi networks on that channel. This Wi-Fi scanner helps you see the best channel for Wi-Fi.

inSSIDs help you find out which security setting your Wi-Fi is using, reducing the risk of unauthorized access to your home network.
