The part of the url that pops up between the / and the : is your Wii U's IP address.
Wow don't I feel foolish.
Okay, this should be last question.
But I still can't connect, and here's exactly what I did:
1. Open Wii U Browser and got to loadiine.ovh
2. Select the first option which is Homebrew Launcher 1.2 RC3
3. Brings me to the Homebrew menu. I select loadiine
4. Now, there's nothing on loadiine (since I have a disc, I guess), but I set the launch mode to Wii Maker as I saw someone say that once
5. Then, I hit the home button 2, once to return to the Homebrew, and the second to back out of that, and be taken to Mii Maker.
6. From there, I get to the home menu and start up X.
7. At this point, I tried connecting on the start screen, the main menu, and in the actually game standing where I last saved. None of those worked.
So, am I missing a step, or is it completely messed up, or I just don't know? Granted, I am entirely new at this as I started last night~
