Chapter 9 - Troubleshooting
Problem #7
Sometimes when I try and use the Internet or get my mail, the application can’t connect to the
Internet immediately.
•
The most common reason for this is not due to a problem or error. If you are the first person to
make a connection to the Internet through the RF500S, there will be a delay when the Dial-On-
Demand function automatically makes the connection and logs on to your ISP. Subsequent users
will be able to use the connection you’ve established without a delay.
•
If the scenario described above does not fit your situation, use RouteFinder monitor to view all
events that are taking place between the modem and your ISP as you attempt to make a
connection (e.g., a busy signal).
Problem #8
After installing my RF500S, my modem connection seems to be slower.
•
The RouteFinder device should have no effect on the modem speed. However, if more than one
client is using the same modem through the RouteFinder, the speed will be reduced.
•
Run RouteFinder Monitor to view the number of concurrent client connections to your ISP.
Problem #9
While the Serial async port is in use, my RF500S keeps dialing a connection to the Internet, but
no one is using the Internet.
•
The RF500S will only dial the connection if there is a request from one of the computers on the
LAN for an IP address on the Internet. Keep in mind that certain applications can be configured to
request information from the Internet. For example, Microsoft Outlook can be set up to “check for
new mail every x minutes”. If this feature is enabled, Outlook will send a request for your Internet
POP3 server which will cause your RF500S to dial-up your ISP. To determine which computer on
your network is processing a request for an Internet connection, use the RouteFinder Monitor.
The event messages will provide information about which computer is causing the RF500S to dial
and which service (port#) the computer is requesting.
Problem #10
The “Please set the Device IP” screen displays when configuring the RF500S.
•
This system detects that the RouteFinder’s LAN Ethernet IP address is not in the same subnet as
the PCs. Use RouteFinder Manager to set the RouteFinders’ IP address to the same network as
your PC’s.
Problem #11
A message appears indicating the IP address you have inputted is either not valid on your
network or is in conflict with another IP address.
•
The manager has detected the IP address of the RF500S you are configuring is in conflict with
another device. Power off the conflicting device and configure the RF500S using a different
Ethernet LAN IP address.
