Yesterday we received delivery of our new Cisco 2821 router. We mounted in the rack, started it up and via ethernet were able to ping the router (using the default 10.10.10.1 address). Something must have happened o/night as now i cannot ping the router. My network connections shows 1GB connection but it gives an error "Request Timed Out" it seems as tho it has lost its factory settings. any way of getting these back? it has a CF card installed.
