Since around 6 months after I bought my PS3, my wifi was very very very very slow.
Eg a 1GB demo takes a whole night to download, and recently took a whole day!

So I discovered this hack.

I opened up the thing and moved my wifi hardware from the back of the machine to as far front as it possibly could be put.

Now a 1.3gb download just took 12 minutes.

Oh I also installed a very old 120GB OCZ Vertex II just for fun.

*school holidays must have driven me a bit over the top*

I hope this lasts ...
