What is WifiInfoView?
WifiInfoView lists nearby wireless networks with their SSIDs, MAC addresses, signal quality, RSSI, frequency and channel. Use it to compare the access points your Windows wireless adapter can see, or switch to a summary view to group networks by channel, manufacturer or signal quality. Selecting a network reveals its Wi-Fi information elements in a lower pane.
The utility runs without an installation process and can export network details as CSV, HTML, XML or JSON. It also exports selected access points to a PCAP file for analysis in Wireshark; the publisher describes this as one beacon frame per selected access point, not a continuous traffic capture.
Results depend on your wireless adapter and driver. A 5 GHz-capable adapter is required to see 5 GHz networks, and router names or models appear only when the router supplies them. On Windows 11 24H2 onward, location access must be enabled for WifiInfoView to read Wi-Fi information; otherwise it can report Error 5: Access is denied.
