If your computer has been given a proper IP address, make sure that the IP
address is in the same subnet as the IP address of the AP25N01. If it is, click
Start , click Run , Type "CMD" in the dialog box and press Enter . At the prompt,
type “Ping x.x.x.x” (where the x’s equal the IP address of the AP25N01). You
should receive four replies, which indicates that you have a proper connection to
the AP25N01. Change your computer’s IP address back to the normal setting.
You should then be able to “ping” the IP address of any device farther back in the
network (another router, modem, etc.). If you are unable to ping a device farther
into the network, then you don’t have a connection between the AP25N01 and
the next device.
Troubleshooting a TCP/IP Network Using a Ping Utility ???
Most TCP/IP terminal devices and routers contain a ping utility that sends an echo
request packet to the designated device. The device then responds with an echo reply.
This makes troubleshooting a TCP/IP network very simple.
Testing the LAN Path to Your AP
You can ping the AP from your computer to verify that the LAN path to your AP is set up
correctly.
To ping the router from a PC running Windows:
1. From the Windows toolbar, click Start and select Run .
2. In the field provided, type “ping” followed by the IP address of the router, for
example:
ping 192.168.2.254
3. Click OK .
You should see a message like this one:
Pinging <IP address> with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out
If the path is not functioning correctly, you could have one of the following problems:
