They are not correct. I didn't make any mistake. I read all the instruction I could find and all of them say:
> "Use the following IP address" and enter IP address 192.168.15.201, and 255.255.255.0 for the subnet mask, click OK twice. Open your remote terminal application, and connect as root to the address 192.168.15.244

This didn't work with my K3.
