Troubleshooting Connection Problems
If the Web configuration page does not come up with the instructions given in the last two sections,
there are several things which can be done to troubleshoot connection problems.
Unable to Load Web Page
If the Web configuration page fails to load, the following are common reasons why this might happen.
1. Due to network configuration, the computer making the connection may not be able to reach the
ZyWAN-G9. Check connection to the Web page by doing a ping command (see Ping the ZyWAN ,
on page 37 ). However, if trying to connect over the Internet/cellular connection, a ping may fail
because it is blocked by the cellular network. In this case, try making an SSH connection with the
PuTTY application (see SSH Client, Terminal Program (PuTTY) on page
26 for help installing
PuTTY), because the SSH connection should work if a connection can be made to the ZyWAN-G9.
2. Over the Sprint network in the United States, it may be that port 80 is blocked. In the Web
browser, try entering the full HTTPS address of the ZyWAN-G9 ( https:// ip_address /cgi-
bin/php/main.php , where ip_address is the address of the ZyWAN-G9), which may work to load the
Web page.
Ping the ZyWAN
To ping the ZyWAN, complete the following steps:
1. In the Windows Start menu, select Accessories>Command Prompt. The Command Prompt
window is displayed.
2. Type the command:
ping address
where address is the numeric address of the ZyWAN-G9.
A diagnostic message is sent to the ZyWAN-G9 to check communication. If successful, the Ping
response receives the following reply.
