I have a very strange problem, I have 2x  1721 routers , exact model, when i use adsl wic on one, it works fine, when i use it on the other, it doesnt recognise the ATM interface.

The only difference between the 2 is that one of the 1721 is newer.

Anyone know the technical reason why it doesnt work??
Watch Question

Check the Flash Memory size of both the Routers

and also the IOS Version



I will double check this and will write back, i have a sneeky suspicion its the IOS.
How did it go?
