[SLL] USB WiFi and Linux (rt2870)

I've got a project here where I am trying to get a USB WiFi adapter
working with Fedora 9. I've got a WUSB600N and an Edimax EW-7718 which
both use the ralink ra2870 driver. The 600N needs a patch so that its
USB ID is recognized, the 7718 doesn't.

The are recognized by the system, show up in lsusb just fine, and when I
install the rt2870 meta package iwconfig the other iwtools show their
status.

But for the life of me I am unable to get either of them to work
(defined as connecting to an AP and getting an IP).

I have a brand new Linksys AP here that isn't connected to anything. It
is setup in open mode. Both adapters see it and when I try to connect
(using either the iwpriv commands suggested by the ra2870 docs) or the
/etc/Wireless/RA... setup file -- but when I run iwconfig repeatedly I
can see them associate with the AP (showing its SSID and MAC) and then
they drop it. And re-associate, then drop. I can't get an IP from it at all.

When trying to associate with my WPA2 protected AP the association looks
good and stable. Repeated runs of iwconfig always show its SSID and MAC.
Connection quality is good (100/100). But setting the encryption key
doesn't work! iwconfig continues to show no key and it won't get an IP.

Has anyone successfully used a rt2870 based USB WiFi? Do you have any
suggestions as to what to try? I'm pretty well out of ideas. Everything
I see on the net says 'It works'. Everything I try says 'its a POS'.

Thanks,

Brian
