Man o man! Finally have a cable now instead of a wireless connection. But it was damn hard.
First I had to lay the cable from downstairs to my room, drilling holes in the process.

Then I still had to make an UTP cable out of it, with the plugs or whatever. But I didn't have the tool or the parts. Finally got them, turns out the tool doesn't work!!! A few days later I finally got what I needed... CABLE DOESN'T WORK!
So I thought I'd reset the router. So I did, and then the phone and internet didn't work!!! AAAH! We've been without phone for a day, when I finally found out about a hard reset. So I did it, and yes phone/internet was back. Cable STILL didn't work!
Turns out I did something wrong with the wires of the cable...

So now it works! *sigh* And my internet finally works like it should.
So I'm gonna try running an AVP2 server on saturdays soon.
