I am a moron when it comes to issues with the computer that doesn't involve MSN, EoFF or Minesweeper. Unfortunately, the remaining area is quite big. Please help me, and when explaining to me how I should do it, explain it as if I was retarded. I'm not, honest. But let's just pretend I am.

I don't know what information is relevant so I'll just provide everything I know. I'm using a Gigaset 551 router. I live in an apartment complex along with lots of other students. To connect to the internet, I just connect an ethernet cable to an ADSL outlet in the wall. There's no modem or anything in my room. This is the outlet I connected the router too.

I have gotten my router connected to the internet, the problem here is that I can't seem to be able to secure it so no one else can use it. In visuals, this is my problem:



And for the record, I had to choose Dynamic IP to be able to connect to the internet. The other options wouldn't let me. Is this ok?

This next part contains the Securing wizard. I can't seem to be able to finish this.



In this one I usually click Off, although I've tested On also.



In this one I have no clue what to pick, so I just go with whatever and the field underneath it is just a key I chose myself right?

The next screen is when I finish the wizard and save my work, and also the place where everything goes horribly wrong. At this point I get disconnected. Not only do I get disconnected, I also can't find my network in the list of closed and open wireless connections in the area, so there's really no other way for me to get back to my net other than reset the sunnovabitch and try over again. Something I've done twenty times now.

For the love of all that is good in the world, help me EoFF.
