Chapter 7 – Troubleshooting
This chapter provides a list of common problems encountered while installing, configuring, or administering
the MultiModem iSMS.

MultiModem iSMS Troubleshooting

Other computers can connect to the network device, but my computer can't.
•
Whenever I click on Internet Explorer or Netscape, I see the Windows Dial-up utility popping up on my
screen asking my phone number and password to dial-up my ISP. To correct this, remove the TCP/IP
dial-up adapter from all computers that will be using your MultiModem iSMS. TCP/IP dial-up adapter is
not needed to access the MultiModem iSMS.
1. To remove the Dial-up Adapter, click Start | Settings | Control Panel.
2. Double-click the Network icon.
3. Click the Dial-up Adapter and click Remove. Restart the computer and try again.
•
Ensure your PC has a correct IP address. From a DOS window in Windows 95/98, type WINIPCFG or
from newer Windows operating systems, type IPCONFIG. If the address field is listed as 0.0.0.0, the
computer does not have an IP address. Enter a statically assigned IP address.
•
Ensure that the Web browser is properly configured to connect to the MultiModem iSMS via the LAN.
The MultiModem iSMS is connected, but my workstation has problems accessing the MultiModem iSMS.
•
Ensure the workstation has TCP/IP properly configured.
•
Attempt to ping the IP address of the MultiModem iSMS.
•
Use WINIPCFG (Windows 95/98) or IPCONFIG (Windows NT/ 2000) to check to see if the computer's IP
settings are correct.
•
Ensure the DNS settings are correct.
•
Ensure the Gateway IP address is the device's LAN Ethernet IP address (Server IP address).
•
Ensure the IP address netmask is correct.
It appears that the MultiModem iSMS cannot communicate with the cellular modem.
•
Check your initialization string.
•
The Status LED and LS LED should be blinking.
•
Review the wireless modem account activation instructions to make sure they were properly executed.
Authenticated triggers are not being executed.
•
Is the SMS trigger text message sent to the MultiModem iSMS worded as configured?
•
The phone number of the device sending the SMS trigger message (word or code) must be included in
the list of authenticated users and the phone number must be preceded with the country code. For
the U.S., enter "1". This allows authentication to work properly by allowing the MultiModem iSMS box
to successfully match the cell phone number of a received trigger message with the phone number in
the authentication list.
