OK, the fact that you have to enter an IP address is odd to me. Yes, you do have that option, but I have never had to use it. Your signature is not clear, what is your DAW? Certainly you don’t have Cubase on an iPad?
I can’t speak to Mac if your DAW is Mac, but for PC the only thing I can think of to solve your problem is to make sure you have a clear path to your router. When this is the case, there is no need to enter an IP address. If you are Windows, search networks, public and private and how to set them up. I would bet that your OS is blocking the Ski remote.
