I have installed the Cisco 1721 with WIC-1ADSL and VPN module and configured to connect to the Japan network over VPMN from India.
WAN link is ADSL.(bridging mode)
It works fine,but suddenle I lose the CD in the ADSL interface card,and I lost the connectivity,if it works it works fine for say 4 to 5 days,If it lose the CD then I struggle to get the connectivity.When the CD is not detected that time if I replace the Cisco 1721 router with the ISP provided ADSL router then it get connected to the Internet.
This is not a permanent problem,it is a intermitent problem.
Could u please guide me?
Thanks and Regards,
