Hi I was thinking of purchasing Airport extreme download for $1.99 at Apple.com I'm not sure once I purchase this thing will I be able to get better wireless connection than before? The reason is that I have a PS3 in wireless mode and the downloading speed is very slow compared to my computer. I don't want to wired my ps3 each time just to get a small boost in downloading, while my imac is disconnected at the moment. I have heard using PS3 proxy would lead to a faster connection, but the ps3 say failed on each attempt. Also if I do purchase airport extreme and while running it will my PS3 fail to establish a wireless connection?
