Multiple clients on ath0 authentication failure

Using versions
hostapd 0.5.7

I think madwifi is built into my ubuntu gutsy restricted kernels.  I can't
seem to get the version.  This has previously worked ok with some linux
clients.  but at the moment I can't get my Nokia N800 to connect, or my
laptop.  A windows XP machine however connects fine as shown below.  I'm
really not sure what's happening here.  Occasionally clients will connect
but it usually takes a few tries.  At the moment however no linux based
clients seem able to connect.

Any help very much appreciated
