Try going onto the Samsung window and search for more printers. The Samsung always keeps changing it's compatible code, which is very annoying. The code should be something like 192.168.1.20. I had that compatibility problem myself. The 192.168.1.68 wouldn't work, so I used the 192.168.1.70. When that wouldn't work, I used 192.168.1.72, then I used 192.168.1.66. Finally, when THAT wouldn't work, I used 192.168.1.73, but that is subject to change. Hope this helps.
