Troubleshooting
This appendix suggests solutions for problems you may encounter in installing or using the RX3141, and
provides instructions for using several IP utilities to diagnose problems.
Contact Customer Support if these suggestions do not resolve the problem.
Problem Troubleshooting Suggestion
Power LED does not
illuminate after
product is turned on. Verify that you are using the AC adapter provided with the
device and that it is securely connected to the RX3141 and a
wall socket/power strip.
LINK WAN LED
does not illuminate
after Ethernet cable
is attached. Verify that an Ethernet cable like the one provided is securely
connected to the Ethernet port of your ADSL or cable modem
and the WAN port of the RX3141. Make sure that your ADSL or
cable modem is powered on. Wait 30 seconds to allow the
RX3141 to negotiate a connection with your broadband modem.
LINK LAN LED does
not illuminate after
Ethernet cable is
attached. Verify that the Ethernet cable is securely connected to your LAN
hub or PC and to the RX3141. Make sure the PC and/or hub is
turned on.
Verify that your cable is sufficient for your network requirements.
A 100 Mbit/sec network (100BaseTx) should use cables labeled
Cat 5. 10Mbit/sec cables may tolerate lower quality cables.
Internet Access
PC cannot access
Internet Use the ping utility, discussed in the following section, to check
whether your PC can communicate with the RX3141’s LAN IP
address (by default 192.168.1.1). If it cannot, check the Ethernet
cabling.
If you statically assigned a private IP address to the computer,
(not a registered public address), verify the following:
• Check that the gateway IP address on the computer is
your public IP address (see the Quick Start Guide
chapter, Part 2 for instructions on viewing the IP
information.) If it is not, correct the address or configure
the PC to receive IP information automatically.
• Verify with your ISP that the DNS server specified for the
PC is valid. Correct the address or configure the PC to
receive this information automatically.
• Verify that a Network Address Translation rule has been
defined on the RX3141 to translate the private address
to your public IP address. The assigned IP address must
be within the range specified in the NAT rules. Or,
configure the PC to accept an address assigned by
another device (see section 3.2 "Part 2 — Configuring
Your Computers”). The default configuration includes a
NAT rule for all dynamically assigned addresses within a
predefined pool
