31Ubiquiti Networks, Inc.Chapter 3: AirOS™AirRouter User GuidePingThe Ping tool is used to check the preliminary link qualityand packet latency estimation between two networkdevices using ICMP packets.Network PingSelect Destination IP A remote system IP can be selectedfrom the list which is generated automatically or can bespecified manually.Packet Count Enter the number of packets to send forthe ping test.Packet Size The size of the ICMP packets can be specifiedin this field.Start The test is started using this button.Packet loss statistics and latency time evaluation isprovided after the test is completed.TracerouteThe TraceRoute tool allows tracing the hops from theAirRouter to a selected outgoing IP address. It should beused for finding the route taken by ICMP packets acrossthe network to the Destination host.Destination Host Enter the IP address of the destinationhost to which you want to find the route.Resolve IP Addresses Resolution of the IP addresses(symbolically rather than numerically) can be enabled byselecting this option.Start The test is started using this button.Speed TestThis utility allows you to test the connection speedbetween two UBNT devices that are using firmwareversion 5.2 or above. It should be used for a preliminarythroughput estimation between two network devices.Select Destination IP A remote system IP can be selectedfrom the list, which is generated automatically (Selectdestination IP) or may be specified manually.Remote system access credentials (administratorusername - User and Password) should be provided forthe communication between two AirOS powered devices.This is required in order to establish the TCP/IP basedthroughput test.Remote WEB port The remote Web port the AirOSpowered device should be specified in order to establishTCP/IP based throughput test (i.e. 443 port should bespecified if HTTPS is enabled in the remote system). TheICMP throughput measurement routine will be initiated ifthe WEB port of the remote system is incorrect.Show Advanced Options Enables additional Speed Testutility options. There are 3 options available for the trafficdirection while estimating the throughput maximum:Direction There are three directions to choose from:• Duplex Estimates the incoming (Rx) and the outgoing(Tx) throughput at the same time.• Receive Estimates the incoming (Rx) throughput.• Transmit Estimates the outgoing (Tx) throughput.Test Results Displays three result categories:• Rx Displays the estimated incoming throughput.• Tx Displays the estimated out-coming throughput.• Total Displays the aggregated throughput.AirViewAirView is a Spectrum Analyzer allowing you to see thecrowdedness of the radio spectrum. You need to run thistool on a system connected to the AirRouter via Ethernet.All wireless connections will be disconnected from theAirRouter.Note: Launching AirView will terminate allwireless connections on the device.
