Initialization of the PVC connection failed when I connect to WAN.

Ensure that the telephone cable is connected properly from the ADSL port to the wall jack. The ADSL LED on the top panel of the router should be on. Check your VPI, VCI, encapsulation type, and type of multiplexing settings are the same as those provided by your ISP. Reboot the router. If you still have problems, you may need to verify these settings with your ISP.
