Chapter 6:Troubleshooting Chapter 6: Troubleshooting If the suggested solutions in this section do not resolve your issue, contact your system administrator or Internet service provider. Problems with LAN PCs on the LAN can not get IP addresses from the ADSL Router. The chances are that the interface used as DHCP server is modified and the client PCs do not renew IP addresses.
Chapter 6:Troubleshooting If you get a failed ping with the response of: Request time out Then the DNS is not reachable. Check your DNS setting on the ADSL Router. Problems with Upgrading The following lists the error messages that you may see during upgrading and the action to take. Error: All the ADSL LEDs light up and cannot light off as usual.
ADSL Router User Manual Error Message: transfer time out Possible cause: The transfer session is interrupted. Action: a. Make sure the TFTP server is on the same subnet with the ADSL Router. b. Make sure you the IP address of the TFTP server you specify is correct and that your TFTP server is started. c. If error still occurs, reboot your ADSL Router and perform the upgrade task again. Error Message: firmware update in process Possible cause: The upgrade is already in process.
Chapter 6:Troubleshooting 65
Chapter 7: Glossary Chapter 7: Glossary ARP (Address Resolution Protocol ) ARP is a TCP/IP protocol for mapping an IP address to a physical machine address that is recognized in the local network, such as an Ethernet address. A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host on the network that has the IP address in the request then replies with its physical hardware address.
Glossary Private IP Address Private IP addresses are also LAN IP addresses, but are considered “illegal” IP addresses to the Internet. They are private to an enterprise while still permitting full network layer connectivity between all hosts inside an enterprise as well as all public hosts of different enterprises. The ADSL Router uses private IP addresses by assigning them to the LAN that cannot be directly accessed by the Internet or remote server.
