Troubleshooting
This chapter provides a list of common problems encountered while installing, configuring or
administering the RF802EW. In the event you are unable to resolve your problem, refer to the
Service, Warranty and Technical Support chapter of this User Guide for information about contacting
our Technical Support representatives.
Common Problems
Problem #1
My computer can’t detect my RouteFinder on the LAN when I start one of the RouteFinder
Utilities (Device Not Found).
• Try clicking Refresh Device List.
• Unplug your network device and plug it back in, then press Refresh Device List.
• Ensure your computer has TCP/IP properly configured. You can check this by trying to “ping”
the computer you are using. If you can successfully ping the computer from itself, the computer
has TCP/IP correctly installed. Once you determine that you are able to ping the computer, try to
ping another computer in the same segment of your network. If this ping is successful, your
computer is properly connected to the network.
• Remove the TCP/IP Dial-up Adapter from your computer. For instructions, see Problem #2 in
this section.
• Ensure your network device is properly connected to your Ethernet hub by pressing Refresh
Device List in either RouteFinder Manager or RouteFinder Monitor. If your RouteFinder is
correctly connected, the WAN indicator light on your RouteFinder will flash. If no flash occurs, it
is not properly connected to the network. Reconnect your network device to the hub and try
again. If there is still no flash, it is possible the Ethernet cable or hub has a problem.
Problem #2
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 for my phone number and password to dial-up my ISP.
• Remove the TCP/IP dial-up adapter from all computers that will be using your RouteFinder to
access the Internet. TCP/IP dial-up adapter is not needed to use the RF802EW to connect to the
Internet.
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 press Remove. Restart the computer and try again.
• Ensure you have a correct IP address. From a DOS window in Windows 95/98, type winipcfg.
From Windows NT, type ipconfig. If the address is listed as 0.0.0.0, the computer does not have
an IP address and you must ensure the automatic DHCP configuration has been correctly set up
for this computer.
• Ensure that the Web browser is properly configured to connect to the Internet via the LAN.
