**WiFi Scan** **WiFi Scan**
Displays a list of other 802.11 signals that your node can see. The 802.11 signals may include Access Points, neighbor nodes, and other mesh networks (foreign ad-hoc networks), but only if they are using the same bandwidth settings as your node. When multiple ad-hoc networks are visible (with different SSIDs or channels), the *network* is displayed but not the individual nodes. There is also an automatic scan mode, but running a wifi scan continuously is not recommended because this will degrade mesh performance. A wifi scan transmits queries on all channels to discover other devices. Displays a list of other 802.11 signals that your node can see. The 802.11 signals may include Access Points, neighbor nodes, and other mesh networks (foreign ad-hoc networks). WiFi Scan only finds devices on the same channel width as your node is configured to. When installing at a new location, it is best practice to scan on 5, 10, and 20MHz channels to find all 802.11 signals in range. This information will help to pick a channel clear of other interference. When multiple ad-hoc networks are visible (with different SSIDs or channels), the ID of each 802.11 ad-hoc *network* is displayed but not the individual nodes. There is also an automatic scan mode, but running a Wifi Scan continuously is not recommended, particularly if the node is actively routing traffic. The scan is passive, or only listens for other beacons through all channels, and risks loss of data on the assigned channel. Wifi Scan does not transmit probes on every channel in passive mode, thus no risk of interfering with Radar stations on DFS channels, or other unintended transmissions. Multiple attempts of Wifi Scan will be necessary to find all devices in range.

The username is always ``root``, while the password is the one you set during initial node setup. If the node has not yet been configured, the password is ``hsmm``.
