![]() ![]() ![]() The sendor sends an ECHO ICMP message (TYPE 8 ICMP message) to the target IP address. Ping is used to attempt an Internet Control Message Protocol (ICMP) communication with a remote host based on the IP address. Ping - most OSes and switches/routers have this feature.Some tools that analyze conneciton issues and view client device parameters, settings and cabailities include ping, traceroute, pathping, nslookup, netstat, and netsh (win32). TamoSoft Throughput Tester - this is a GUI based throughput tester that can test both TCP and UDP traffic.To test the uplink, the wireless client should be configured as the iperf client. So, if you're testing a wireless client, to test the downlink, the wireless client should be configured as the iperf server. typically the default behavior of iperf is to test the throughput from the client to the server. iPerf3 - this is a client/server throughput tester.On a WLAN, useful throughput is always less than the data rate because of management traffic overhead. To repeat, throughput is not a simple factor of data rate. The contention for the wireless medium must also be considered. Data rate is a major factor in determining network throughput for a user, but it is not the only factor. Higher data rates use more sophisticated modulation and coding schemes and require better RF/signal conditions than lower data rates. Data rate is the rate at which bits can be sent across the wireless medium, and is entirely dependent on signal quality and the modulation and coding scheme ( MCS) used. When testing wireless (802.11) throughput, remember that you're not testing data rate. ![]()
