Check if both the LEDs of Local and Global on the product’s front panel are green. If yes, go to next step. Otherwise, make sure you are using the correct cables and the cables are connected to the network devices properly.
Check the physical connectivity of the broadband device.
Examine the LED of LAN port and the LED of the broadband signal input on the Cable Modem/xDSL Modem. If the LAN LED is off, make sure you are using the correct cables and the cables are connected to the devices properly. If the LED of the broadband signal is off, please contact your ISP.
Note: You can also call your ISP and make sure the Internet service is still online.
Check the status of this product.
If your ISP assigned you an IP address, please skip this step. Otherwise, use the HyperTerminal program to “release” and “renew” the current IP address of the Global port. After that, type “Show” command to see if “obtain global port configuration from ISP” shows the address is “claiming” or “under claiming”. If the IP address is “claiming”, go to next step. If the result is “under claiming”, reboot the product and check it again. If the result still is “under claiming”, please contact your ISP and find out if the service is still available.
Check the logical connectivity from your computer to the Internet.
