Wifi hotspot game problem..?

[HawkZone]

Hello! Wats up dudes.
I just wanted to ask, I got a wifi in my place that doesnt have any protection, but when you go to the internet, you need to enter a username and password. I know the username and even a password, but the problem is, that when I enter it on the PSP and then exit the internet app the psp doesnt remember that its connected so it disconnect immidiately. Then when I go to the game I cannot play online. Please any help?
