34Modem Troubleshooting Problem with Modem Powering ONProblemTroubleshootingNone of the LEDs will glow when the Modem is Powered ONMake sure that the Modem’s power adaptor is connected to the Modem and plugged in to an appropriate power source.Check that the power source for the Adapter is OK.Check the DC Voltage of Power Adapter Output. If the Output is OK then it could Problem of Modem Hardware. Modem need to be sent to SemIndia for repair or replacement.If the Output is not OK then it could be Power Adapter Problem. Power Adapter need to be sent to SemIndia for repair or replacement.
35Modem Troubleshooting Problem with the LAN LEDProblemTroubleshootingLAN LEDs do not turn ON for EthernetCheck Ethernet cable connections from Modem to PCs.Change the Cable and check for connectivityCheck with the Other Ports on the same ModemMake sure PC’s Ethernet card is working properly.If above checks failed then it could be a problem with the Ethernet Port and Modem need to be sent to SemIndia for repair or replacement.If the Output is not OK then it could be Power Adapter Problem. Power Adapter need to be sent to SemIndia for repair or replacement.
36Modem Troubleshooting Problem with LAN InterfaceProblemTroubleshootingCannot access the Modem from the LANCheck the LAN LED Status. If not OK refer to LAN LED TroubleshootingMake sure that the IP address and the subnet mask of the Modem and your computer(s) are on the same subnet.
37Modem Troubleshooting Problem with the DSL LEDProblemTroubleshootingDSL LED is OFFCheck the connections between the Modem DSL port and Splitter and between Splitter and the wall jack are proper.Make sure that the telephone company has checked your phone line and set it up for DSL service.Try removing ADSL line from the modem and reinserting back to reinitialize the link to the DSLAM.If the error persists, it could be hardware problem. Modem need to be sent to SemIndia for repair or replacement.
38Modem Troubleshooting Problem with the WAN InterfaceProblemTroubleshootingI cannot get a WAN IP address From the ISP.Usually Modem gets the WAN IP address from DHCP Server on the WAN Side after the Modem is authenticated by the ISP with the credentials configured on the Modem. Authentication may be through the user name and password, the MAC address or the host name.The username and password are applicable to PPPoE and PPPoA encapsulation only. Make sure that you have entered the correct Service Type, User Name and Password (User Name and Password are case sensitive).
39Modem Troubleshooting Problem with the Internet AccessProblemTroubleshootingCannot access the Internet.Make sure the Modem is turned ON and connected to the network. If the DSL LED is OFF, refer to the Problems with the DSL LED section.Verify WAN settings, Make sure you entered the correct user name and password.Check with the ISP NOC if there is any change in the settings.
40Modem Troubleshooting Problem with the Login PasswordProblemCorrective ActionUnable to login to the Modem Web Page.The username is “admin”. The default password is “admin”. The Password and Username fields are case-sensitive.
