Did the WPA thing.
I'll try the channel thing tomorrow as the router is set up via my dad's computer.
Tried the router placement thing already.
The router is placed in my dad's room and I don't go there

Plus, he doesn't really care about my predicament and I wouldn't be able to convince him to move it.
Yeah, I was waiting for his answer.
Trannies. That's all.
Thank you all for your help and if it doesn't work, I will be back to bug you again.
