|I agree with Stuart. There is no such thing as one default IP address for all make of routers. Examples are:|
Linksys routers use 192.168.1.1
D-Link & and Netgear routers typically use 192.168.0.1
Some US Robotics routers use 192.168.123.254
Some SMC routers including Belkin uses 192.168.2.1
and so on.
The bottom line is always read the router documentation.
