So I'm trying to configure access to a network using TTLS, however when I click on the 802.11x tab, it's inaccessible! Nothing happens when I click it, and it becomes greyed out after I click it. I'm worried that I might have to reinstall Leopard, maybe the wireless stack is messed up or something. I've tried Googl'ing this, haven't found a solution yet. I remember at one point it had been working, but it's suddenly become completely unreachable.
