The device list provides an overall view on the devices connected to you LAN. Note the information is compiled out of different sources like WiFi connected clients, DHCP lease, arp table, etc.
Interface: represents the location where the router sees the device. Interface names might be a bit confusing initially.
- br is a bridge (aka LAN)
- eth is a physical interface might be used directly or not if a bridge/ppp/vpn etc are associated to it
- vlan is a virtual interface will always be related to a physical interface. In the example below vlan2 represents the WAN interface
- wl are the radio interfaces, you'll have multiple of these based on the number of radio chips available in your HW (2.4/5GHz) plus additional are created when virtual interfaces are created a.k.a. secondary SSID.
MAC Address: is the physical address associated to the interface.
- [oui] provides additional information on the mac address using an Internet search will try to estimate the HW vendor. NOTE: this function is useful only for HW default addresses and will not perform as expected with manually defined MAC addresses. (you can define MAC addresses for each interface manually using the Advanced/mac addresses page.
- [static] is a shortcut into basic/Static DHCP/ARP/IPT and allows you to defined a DHCP reservation linked to the mac address.
- [bwlimit] is a shortcut to define bandwidth limits for the specific device
IP Address reports on the IP linked to the MAC
Name is the hostname. If a name is missing it can be because your device is not directly connected to the router e.g. via external switch or AP. You can hack this adding your own dhcp-host, reference in the Dnsmasq Custom configuration e.g.
RSSI applies to WIFi clients directly connected only and represents the signal strength. RSSI is measured in negative numbers where 0 is technically the best possible value so in the example below -53 is a stronger signal than -74. If possible kwwp your device away from metal, concrete and mirrors as they all reduce consistently the signal.
Quality is similar to RSSI but it takes into account other parameter like noise floor, interferences etc to give info on the connection
TX/RX Rate is the WiFi negotiated speed. It is very normal to see these numbers going up and down based on the end device activity.
Lease is information from the DHCP server and represents the time left before the lease expires. NOTE: If you hover over the least ime left an optio nto manually remove the lease from the current DHCP lease database appears:
Noise floor reports on the amount of interferences affecting the each physical radio interface. Noise is measured like RSSI in negative numbers. Best possible value is -100dbm any interference will push the value up and decrease the Quality. Note in case you experience a strong RSSI but with a strong Noise floor too the WiFi is likely to be unusable. The main issue is usually other AP transmitting on the same channel, use the Wireless Survey for that. For 2.4GHz there are well known sources of interference like bluetooth, cordless phones, wireless headphones, gadgets, defective electronic devices like an unbranded power supply, microwave devices, etc. for 5GHz there are usually less source type but one to watch out are the DFS channels but it varies on the country/physical location of course.
