Ping using short packets first (default size) to confirm the connection. Then use long packets
(1472 byte packets) to confirm the RF performance. Errors observed on pings with long
packets indicate a high error rate on the channel, caused by low signal levels or interference.
The following describes how to ping the gateway:
1. Open a DOS window.
2. At the command prompt, type ping <aaa.bbb.ccc.ddd> -t -l 1472, where
<aaa.bbb.ccc.ddd> is the Gateway radio IP address and press Enter.
3. Press Ctrl+c to end the test.
NOTE: If this test fails with the long packets, but pinging the Gateway
with the default packet size succeeds, then the connection is
working but is not operating at maximum capacity, possibly due
to poor antenna placement or orientation, poor signal levels, and/
or interference.
The following example assumes the Gateway has an IP address of 172.16.4.1. Replace that
address with the correct gateway address from the ‘ipconfig’ command:
C:\>ping 172.16.4.1 -t -l 1472

Ping Internet by IP address
Use the following test to determine whether the end-user’s PC can communicate with the
Internet. If you do not know an IP address, try the DNS servers. Otherwise, skip this step.
