You will see a simple Out-GridView table containing information about the parameters of all available wireless networks. $bool=$cmd -Match -Title 'Scan Wifi Script' $bool=$cmd -Match 'Authentication+.(.+)$' The following PowerShell script scans all available Wi-Fi networks (including Windows access points), displays their names, signal strength, channels (useful if you want to find free channels), and supported standards (802.11n, 802.11ac, 802.11g, wlan show networks mode=bssid What is the best WiFi signal strength The WiFi signal strength youll need depends on how you are going to utilize your network. For example, -40 dBm is 0.0001 mW, and the zeros just get more intense the more the signal strength drops. You can also use netsh to also display a list of all available wireless networks in your wireless adapter’s range (not only the list of saved Wi-Fi networks): The most accurate way to express it is with milliwatts (mW), but you end up with tons of decimal places due to Wi-Fi's super-low transmit power, making it difficult to read. You can run this PowerShell code in an infinite loop and check the status of the signal once every 10 seconds, or make it a Windows service that will notify you if the Wi-Fi connection is poor.
