It sounds like the nodes did not image properly. There are many many possible problems, and I am not entirely sure I understand what you have done so I am going to ask many questions.
What hardware are you using? Specifically interested in OS, network cards, and cpu types. 192.168.0.1 is a very common default address for networking equipment. Can you ssh to 192.168.0.1 from another computer on the cluster switch (move one to the switch if the nodes arent booting). Anyway, let me see if I understand what you have done. You have created your image on the head node. Then you have run the "Setup Networking" Step, and successfully collected the MAC addresses of the nodes? or did you enter them in from a file? There is a button on that screen called "Setup Network Boot" which is necessary, did you click on that? If not then the nodes will not image properly. Then did you network boot the nodes again, with a monitor attached and see what happened? Do you have the firewall on the head node turned off? SE Linux off?
