Why does my router work off and on?[SOLVED]

I have a linksys router and every now and then when I try to get it to connect me to Wi-Fi it will work. But then after a day or so, it will stop connecting. So then days from then I try again and it may or may not work again.

Not sure what's wrong with it, don't know if it's the router's location, my wii, or just the router is garbage all together. But I don't think so because my laptop works with it just fine.

The router is in the room across the hall from mine, if you go out the door of my room, to the left and walk a little forward, to your right is my wii on a push cart along with my xbox and ps2. So basically there's a wall between the wii and router if you go a direct route from the router to the wii. I assume it has something to do with the signal from the router having to go around the wall to the wii or something, but I don't know. I don't think it's really the router because my friend has a linksys router and his wii is a meter or two away from it which makes me think it has to do with the position of my router and wii and the wall between them.

So is it the router? The position of the router and the wii? The wii?

Would getting a more powerful router possibly help?

If anyone could tell me what the problem is here please tell me.

EDIT: Well I tried to connect with my ds while near my router and that didn't work so location may not be the problem. And also on a related note, the error code I almost always get on my wii is 51230 and on tech support it says to change the channel my router broadcasts on as well as some other things. If there is another solution besides this please tell me. i don't feel I need to change it because it's worked before but I'll try it. And the ds said 51200 and it said it could have to do with something like transmission rate

EDIT2: Solved. Lock

Come on guys I need some help

That happens to mine a lot... we have the same router... just try to turn it off and on and it'll get back to working again.

Wow can't believe I didn't do that yet. I'll go try it

EDIT: Brawl isn't working but everything else works. So I suppose it's working. Lock please!

Oh the Wii? Yeah, I can barely get mine to work on the 'net either. It's a pain in the rear to try and update it too...
