Anybody else having wireless connection problems with F15 Gnome?

[john wendel]

I've got an old Acer laptop with Intel ipw2200 wireless network. F15 
LXDE works fine on the box, but I'd rather run Gnome (so I can complain 
about how broken it is).

Unfortunately, using F15 Gnome, and NetworkManager, the wireless network 
won't connect. Or rather, it connects and the immediately disconnects, 
repeatedly. I have updated the box to the latest (using the wired 
network), but it's still not working.

Google hasn't been any help, so I'm asking for your help. Anybody?

Thanks,

John
