Troubleshooting
This chapter gives information about troubleshooting your PRT-301W. After each descrip-
tion, instructions are provided to help you diagnose and solve the issue.
LAN LED Not On
If the LAN LED does not light when the Ethernet connection is made, check the following:
- Be sure you are using the correct cable.
- Make sure that the Ethernet cable connections are secure at the Router and at the
hub or workstation.
- Make sure that power is turned on to the connected hub or workstation.
- If you are connecting a LAN port of PRT-301W directly to the uplink (MDI) port of a
hub, use the straight-through network cable.
- If you are connecting a LAN port of PRT-301W to a normal (MDI-X) hub port, use the
crossover network cable.
- If you are connecting a WAN port of PRT-301W to a normal (MDI-X) hub port, use
the straight-through cable.
Troubleshooting the ISP Connection
If your Router is unable to access the Internet, you should first determine
whether the Router is able to obtain a WAN IP address from the ISP. Unless
you have been assigned the static IP address, your Router must request an
IP address from the ISP. You can determine whether the request was suc-
cessful using the Browser interface.
To check the WAN IP address from the Browser interface:
1. Launch your Browser and select an external site such as www.yahoo.com
2. Access the Main Menu of the Router's configuration at http://192.168.1.1
3. Click on Monitor
4. Check that an IP address is shown for the WAN Port
5. If it is "NO" on active table, your Router has not obtained an IP address from your ISP.
If your Router is unable to obtain an ISP address from the ISP, the problem may be one
of the following:
- Your Router may be set incorrectly the login name and password for PPPoE mode.
- Your ISP may check for your PC's Host Name. Assign the PC Host Name of your
ISP account to the Router as System Name, or as Host Name in the browser-based
Setup Wizard.
- Your ISP only allows one MAC address to connect to Internet, and may check for
your PC's MAC address. Inform your ISP that you have bought a new network device,
and ask them to use the Router's MAC address.
If your Router can obtain an IP address, but your PC is unable to load any web pages
from the Internet:
- Your PC may not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www
addresses) to numeric IP addresses. Typically your ISP will provide the addresses of
one or two DNS servers for your use. If you entered a DNS address during
the Router's configuration at NAT mode, reboot your PC and verify the DNS address.
