Cheetah iSharer-3010
This chapter provides the solutions to problems that may occur during installation
and operation of the Cheetah iSharer-3010. Please refer to the following table to try
to solve your problem.
Hardware -
Symptom: The Link LED is off.
Cause & Solution: Check all the connections and make sure that they are firmly
connected.
Remember that Ports 1 - 7 use straight-through cable, but Port
8 can use straight-through or crossover, depending on the
switch setting.
Make sure that your Ethernet card is installed properly.
Symptom: Modem is not able to dial out.
Cause & Solution: Make sure all connectors are firmly attached and the modem is
powered on.
Make sure a working phone line is connected to the modem.
You may need to add a prefix to the number such as a “0,” to
get an outside line. There is a delay of about one second.
Client site -
Symptom: I can’t access the Cheetah iSharer-3010 with a browser.
Cause & Solution: Check the TCP/IP setup on your PC.
Run “winipcfg” under the Windows 95/98 DOS shell or run
“Ipconfig” under the Windows NT DOS shell. The PC should
have an IP address of 192.168.1.x (where “x” is from 1 to 254.).
If you use a fixed IP, you should have to set the client station’s
IP address in the range of 192.168.1.2 ~ 192.168.1.254
excluding 192.168.1.100 ~ 192.168.1.149, the default gateway
as 192.168.1.1, and the DNS IP address to that provided by
your ISP. If the computer has previously used Dial-up
networking for Internet access, you have to make the following
changes:
1. Click “Start”, “Setting” and “Control Panel.”
2. Double click the “Internet” icon and then click the
“Connection” tab.
3. Select “Connection to the Internet using a local area network”
4. Click “OK” to finish.
Cheetah iSharer-3010 and Modem -
Symptom: Modem can dial out, but won’t connect to the ISP.
Cause & Solution: Check the initialization string. Be sure to power off and power
on the modem after changing the string.
Basically, the default AT command is “AT&F” and is available for
most modems, but some modems use their own initial AT
command due to a changeable serial port rate, and you can find
this information in their user’s manual. (For Example, US
Robotics modem initial string is “AT&F1B1.” )
For telephone systems with no dial tone, the initial AT command
should add “X1” as in “AT&FX1.”
Test the modem in the Telnet Diagnostics window.
You can also use the “Ping” command in MS-DOS to verify the
network connection:
•
Ping 127.0.0.1 to see if the TCP/IP stack is properly
configured.
•
Ping the gateway IP (Default: 192.168.1.1) to see if the
network’s internal link works.
•
Ping the DNS IP and observe whether the modem will dial or
not to check the external link and modem connection.
•
Ping an Internet location (Example: www.yahoo.com) to see
if the DNS works.
Symptom: When dialing into the Cheetah iSharer-3010, the Modem does
not seem to connect.
Cause & Solution: Make sure that you are on the Cheetah iSharer-3010’s “Dial-in
User” list.
Symptom: Modem 2 cannot be enabled.
Cause & Solution: Check the rear panel of the device, the MODEM2/CONFIG
Switch must be set on MODEM2. If the Bandwidth-on-Demand
is enabled, lower the threshold for MODEM1 in the dialog box
(the default setting is at 50%).
Miscellaneous -
Symptom: I cannot get an IP from the Cheetah iSharer-3010. I have
another DHCP server on my LAN.
Cause & Solution: If there is no Internet access for your network environment, we
suggest that you disable the hub’s DHCP server on the Intranet
page. If your LAN can now access the Internet, we suggest that
you disable your pre-existing DHCP server services or separate
them into a different segment.
