PS Store Download Wired VS Wireless

I was trying to download a demo of 500mg, wireless. It was so slow I was in the 2000 minutes left. I decided to try wired, and in 10 minutes it was done. I mean how can it be possible? I am not lagging online in any games. Is this on my side only or PSN is acting a bit strange with wireless lol?

It's your wireless connection, check your router.

I download stuff at about 2000kbps wirelessly. im a floor down and about 12 feet horizontally from the router
