+WAN interfaces are shown with black and white inverted. A greyed-out power icon represents a device that is disconnected or off.
-  * Clicking on the MAC address opens a web search to try to identify the hardware vendor based on the device's OUI ([[https://en.wikipedia.org/wiki/Organizationally_unique_identifier|Organizationally Unique Identifier]]). The OUI is derived from the first 6 digits of its MAC address. This function is useful only for hardware default (factory-programmed) MAC addresses and will not work as expected with manually-configured MAC addresses as they can be arbitrarily assigned.

-\\ **IP Address** displays the IP address linked to the MAC address of the client device. If no IP address is shown, one is not assigned/known yet. This can briefly happen during the authentication phase of wireless devices, even if the wireless password is incorrect.

-**Name** shows the DHCP Hostname of the client device. If no name is shown, it is typically because the device got its DHCP lease on the network from a different router, or this router was rebooted after the lease was given. You can work around this by adding your own dhcp-host reference in the dnsmasq Custom configuration.

+**RSSI:**  This shows Relative Signal Strength. It applies only to WiFi clients connected to this router.
+RSSI is measured in negative numbers, where 0 is the best possible value. Thus, -53 is a stronger signal than -74.
+**Quality: **This is similar to RSSI, but considers other parameters, like noise floor, and interference. Quality is a more accurate assessment of the signal.
+**TX/RX Rate: **This is the current transmit/receive link speeds between router and WiFi client device. It is normal for these numbers to fluctuate based on activity level of the client device and the quality/distance of the signal.
+**Lease: **This displays the time remaining before a DHCP lease expires. The lease time is also a hyperlink. Clicking on it lets you delete the current DHCP lease from the database, and deauthorize the device (if WiFi-connected). This is useful when creating static IP reservations, to make connected devices refresh their previously automatically-assigned IP to the new, manually-reserved one:

+**Noise floor: **This indicates the amount of interference affecting each physical radio interface.
+Noise, like RSSI, is measured in negative numbers. The best possible value is -100dBm. Any interference will increase the noise value and decrease the Quality.
+If you experience a strong RSSI //and// a strong Noise floor, the WiFi is likely to be unusable. In these situations, the main cause is usually other routers/APs transmitting on the same channel. Use the [[tools-survey|Wireless Survey]] tool to get more information.
+On the 2.4GHz band, common sources of interference include:
-**RSSI** indicates Relative Signal Strength. This applies only to WiFi clients connected to this router. RSSI is measured in negative numbers, where 0 is the best possible value. Thus, -53 is a stronger signal than -74. If possible, keep your wireless devices away from metal, concrete, mirrors, and appliances with large motors or compressors (air conditioners, refrigerators, elevators). They all can consistently reduce signal strength/quality.
+  * Bluetooth devices
+  * Cordless phones
+  * Wireless headphones
+  * Low-quality power supplies
+  * Microwave ovens
-**Quality** is similar to RSSI but considers other parameters, such as noise floor, and interference. This gives a more accurate assessment of the signal.
+ \\
-**TX/RX Rate** is the current transmit/receive link speeds between the router and the wireless client device. It is normal for these numbers to go up and down based on the activity level of the client device and the quality/distance of the signal.
+Typically, there is les interference on the 5GHz band. One source of interference is DFS (Dynamic Frequency Selection) only for certain channels only. DFS is a WiFi function that enables 5GHz WiFi to use frequencies generally reserved for radar. Ironically, DFS was designed to reduce interference. DFS interference varies, depending on the country/physical location of the equipment. If you suspect interference is due to DFS, see Wikipedia's [[https://en.wikipedia.org/wiki/List_of_WLAN_channels|List of WLAN Channels]] for details.
-**Lease** displays the time remaining before the DHCP lease expires. The lease time text is also a hyperlink; clicking on it allows you to delete the current DHCP lease from the database, and deauthorize the device (if it's connected via WiFi). This can be useful when creating static IP reservations, to make connected devices refresh their previously automatically-assigned IP to the new, manually-reserved one:

-**Noise floor** indicates the amount of interference affecting each physical radio interface. Noise, like RSSI, is measured in negative numbers. The best possible value is -100dBm. Any interference will push up the (noise) value and decrease the Quality.
+**Measure**: On certain (mostly MIPS-based) devices, there is an extra button to trigger the measurement of Noise Floor (interference). For more information on the noise floor, see the [[tools-survey|Wireless Survey]] menu.
-If you experience a strong RSSI //and// a strong Noise floor, the WiFi is likely to be unusable. In such situations, the main issue is usually other routers or Access Points transmitting on the same channel. Use the [[:wireless_survey|Wireless Survey]] function to get more information.
+**Network Discovery**: This function is available since release 2021.4 . Network Discovery scans all IP addresses in a range to accurately populate the Device List table. (Default: disabled). If enabled, it remains running for the length of the web interface session. However, it will stop if you leave the Device List menu.
-On the 2.4GHz band, common sources of interference include Bluetooth devices, cordless phones, wireless headphones, low-quality power supplies, microwave ovens, etcetera. On the 5GHz band, there are typically fewer sources of interference. One source of interference is DFS (Dynamic Frequency Selection) but for specific channels only. DFS is a WiFi function that enables 5GHz WiFi to use frequencies that are generally reserved for radar. Ironically, DFS was designed to reduce interference, not increase it. DFS interference varies, depending on the country/physical location of the equipment. If you suspect your interference is due to DFS, please see Wikipedia's [[https://en.wikipedia.org/wiki/List_of_WLAN_channels|List of WLAN Channels]] for details.
+Network Discovery can be set to use the Linux **arping** command or the **traceroute** command. Arping is the preferred setting, as it's faster and uses less resources. However, sometimes, traceroute may perform network discovery more precisely. This is true with Apple devices.
-{{:pasted:20210804-210755.png}} \\
+To the right of the Network Discovery mode is a non-adjustable countdown timer which represents how often the script is run. Essentially, it reflects the ARP cache aging time. Remember that modern WiFi devices may stay connected to the router while in sleep mode. Network Discovery will likely detect those devices, but the Hostname information may not appear until they awaken.

-**Network Discovery**: Starting with release 2021.4, a network discovery function was introduced. It is disabled by default. If enabled, it will remain set for the length of the web interface session, although actual scanning/discovery will stop as soon as you leave the Device List menu. Network Discovery can be set to use the Linux **arping** command or the **traceroute** command. Essentially, the function scans all the IP addresses in range to try to accurately populate the Device List table. Arping is the preferred setting, as it's faster and lighter on resources. However, sometimes, such as with Apple devices, traceroute appears to perform network discovery more precisely.

-To the right of the Network Discovery mode is a non-configurable countdown timer which represents how often the script is run. The countdown is essentially the ARP cache aging time. Remember that modern WiFi devices might stay connected to the router while in deep sleep mode. Network Discovery will likely detect those devices, but the Hostname information may not appear until they are awakened.
