7Ubiquiti Networks, Inc.Chapter 3: AirOS™AirRouter User Guide• Noise Floor Displays the current value of the noiselevel in dBm. Noise Floor is taken into account whileevaluating the signal quality (Signal-to-Noise Ratio SNR,RSSI) while value mean depends on signal strengthabove the noise floor.• CCQ Value represents the quality of the connection tothe Access Point.• Tx/Rx Rate Represents the data rates of the lasttransmitted and received packets.• Tx/Rx Packets Displays the total number of packetstransmitted and received during the connection.• Tx/Rx Packet Rate (packets per second) Representsthe mean value of the transmitted and received packetrate.• Bytes transmitted/received Value represents the totalamount of data (in bytes) transmitted and receivedduring the connection.• Negotiated Rate/Last Signal (dBm) table Valuesrepresent the received wireless signal level along withthe all data rates of recently received packets. “N/A”value is represented as the Last Signal if no packets werereceived on that particular data rate.To reconnect to the AP press the Reconnect button,in order to reestablish the wireless link. The list can beupdated using the Refresh button.DHCP Client(Applicable for Router and SOHO Router in DHCP modeonly.) Shows the device’s WAN IP address, Netmask, DNSservers and Gateway while operating in DHCP Routermode.IP Address Displays the device’s WAN IP address whileoperating in DHCP Client mode.Netmask Displays the device’s netmask when operatingin DHCP Client mode. It is assigned automatically by theDHCP server (not the AirRouter’s DHCP server), whichassigns the WAN IP address to the device.Gateway Displays the device’s gateway when operatingin DHCP Client mode, which is assigned automatically bythe DHCP server (not the AirRouter’s DHCP server).Primary/Secondary DNS IP Domain Name System (DNS)is an Internet “phone book” which translates domainnames to IP addresses. These fields identify the server IPaddresses that the AirRouter uses for translation.DHCP Server Displays the IP address of the DHCP Serverassigning the WAN IP Address to the AirRouter.Domain Displays the domain name.Total Lease Time Shows the total time (validity) of theleased IP address assigned by the external DHCP server.Remaining Lease Time Displays the remaining time ofthe IP address leased by the external DHCP server.ARP tableLists all the entries of the ARP (Address ResolutionProtocol) table currently recorded on the device.ARP is used to associate each IP address to the uniquehardware address (MAC) of each device. It is important tohave unique IP addresses for each MAC or else there willbe ambiguous routes in the network.IP Address Displays the assigned IP address.MAC Address Displays the MAC address of the device.Interface Displays the interface that the device is on.The list can be updated using the Refresh button.Bridge TableDisplays the entries in the system bridge table when thedevice is operating in Bridge mode.The list can be updated using the Refresh button.The Bridge table shows which bridge port the particularstation is associated with - in other words from whichinterface (Ethernet or wireless ) the network device(defined by MAC address) is reachable from. The AirRouterwill forward the packets to that port only (thus saving a lotof redundant copies and transmits).The aging timer shows the aging time for each addressentry (in seconds) - after particular time out, not havingseen a packet coming from a certain address, the bridgewill delete that address from the Bridge Table.RoutesLists all the entries in the system routing table, while thedevice is operating in Router mode.The list can be updated using the Refresh button.AirOS examines the destination IP address of each datapacket traveling through the system and chooses theappropriate interface to forward the packet to. The systemchoice depends on static routing rules – entries, whichare registered in the system routing table. Static routesto specific hosts, networks or default gateway are set upautomatically according to the IP configuration of all theAirOS interfaces.
