What driver are you using? This sounds a lot like what rt2500usb (part of the
rt2x00 project) does, when it associates with an AP at all

BTW, did you really send your wep keys to the world? You may want to change
them...

It's a USB dongle:

Bus 002 Device 004: ID 050d:7050 Belkin Components F5D7050 ver 1000 WiFi

I have moved right next to the AP and notice the same weird behaviour.

Yep. I did manage to get it working with wpa_supplicant (or so I
thought . . . )

# lsmod | grep rt2
rt2500usb 21728 0
rt2x00usb 8576 1 rt2500usb
rt2x00lib 14944 2 rt2500usb,rt2x00usb

Am I on a hiding to nothing? I thought that if it made it into the kernel it
would be alright to use. When I was downloading the rt2x00 from cvs it was a
bit of a hit and miss affair.

Nah, not important. I'm in the middle of nowhere to be honest visiting a
friend. Also, WEP encryption is rather trivial to crack, especially so with
a 40bit key.

Ahh, just noticed this USB unclaimed message in lshw:

*-usbhost

vendor: Linux 2.6.24-gentoo-r8 uhci_hcd
physical id: 1
bus info: usb@2

Should it be so?

The rt2x00 driver works for some chipsets, but the rt2500usb doesn't seem to
work at all. If you check the kernel config you may still see it marked as
experimental. Better to use a CVS build (not in portage IIRC) of rt2570 and a
current kernel than to try with rt2500usb at this time. That is what I am
doing, with wpa using the iwpriv commands.
