Busy hands | Disquiet mind

(The install from the full installation DVD went perfectly!)

Fedora 13 does appear to have drivers that work for my awkward wireless card (kmod-rt2860). I can see the available networks, and I can attempt to connect to them. But there is where it falls down. It isn't authenticating against the network, it just continually asks me for the passphrase. I've seen this behaviour before, on many different versions of Fedora, on many different laptops. But never for my home network before. For some reason NetworkManager just randomly decides not to like some networks. And different ones on different machines at that. The only thing they have in common is WPA security. The internet isn't yielding any useful information. I'm wondering if anyone here has come across this before? Can they point me towards a solution? Broken wireless on a netbook is grounds for changing distro.
