How to put computer and iPad on same local network segment

So my air video will not connect to the servers. I tried troubleshooting and its not my computer, but my iPad. I cannot go to the website where I type in my ip address and the port code thing. It says that it may be that my computer and iPad are not on the same local network segment. Does anyone know how to do this? And could it also be a different problem? Thanks!

Actually I think it might not be my IP address. Does anyone know the problem? And if possible a solution as well? Thanks again!
