Cisco 776 ISDN router wont make data connection

I have a home network connected to the internet thru a Cisco 776 ISDN router. It has worked fine for years, but a couple of weeks ago I was tried to hook up a wireless extenstion using a pair of Buffalo 802.11g units.

I was having trouble getting the 776 to server up DHCP IP addresses. I must have issued a bad command to the 776 (I don't at this point know which one) because later I discovered that the 776 would no longer to make connections to my ISP. Its not that it can't because if I do a manual call command it connects fine. It just wont do it on its own, and even if I do it manually, computers on the LAN still cant connect to the internet.

The only command I remember entering is the

"SEt GAteway <ip>"

command (not the "set dhcp gateway <ip>").

I gave the IP address of the router on the LAN in this commmand.

After discovering the problem I have tried several things including doing a SWL with an old saved configuration and also a "Set default" followed by uploading the old configuration.

The problem only affects data connections. The telephone ports still work fine.

Hello,

can you access the router and issue an 'upload' to get the configuration ? If so, can you post the configuration ?

Regards,

GP
