Sees wireless network, but doesn't recognize password

[ultrastevep]

This happens to me at all hotels and now at a place I am staying at that has wireless. I have been using LL1.08 for about 8 months and at home my wireless authentication password was initially recognized and then always automatically connected, but nowhere else can I get a connection. it'll see the networks, but the passwords are never recognized and I have to always switch back to W7 to connect.
Anyone else see this issue?

Thanks....am planning on loading LL2.0 as soon as we move into our new home and I have time.
