Wireless network problem on Macbook Pro

[cosrocket]

I’m having a wireless network problem running Lion 10.7.1 on a 2011 13” Macbook Pro.

When I’m home I have no problem connecting and staying connected to my wireless network, but when I’m at a wireless hotspot such as Barnes & Noble, Panera etc, I am constantly losing my wireless connection and it goes back to the hotspot sign in page every couple of minutes.

I cannot figure out why this is happening, does anyone have any ideas?

Are you sure they don't have a usage limit timer?
If your MacBook Pro works at home, then it's probably a network issue, not on your side.
