wlan connection problem

[jettt]

I have a D-Link wireless router. When I set the router to WEP encryption, I can access the wireless network from my N800.
But if I set the router to WAP2, my N800 can't connect to it. I just get a connection error.

Any suggestion?

When you set the router to WPA, do you see it appear on the list of possible connections?

If it is visible, what happens when you click on it?

Maybe you could try deleting that router from your list of saved connections, then with the router set to WPA try adding it again?
