Unhappy wpa_supplicant: atheros up & down like a yo-yo, interrupt storms too

Hi

First post since moving from BSDForums...

I have a new FreeBSD 7.0 STABLE build on my Dell Inspiron 8600 laptop, retro-fitted with an Atheros 5212 wifi card. As soon as I start wpa_supplicant I get this in .../messages:

Continually checking ifconfig ath0 shows that the connection associates for a few seconds then drops and scans various alternative channels before eventually associating then dropping again, ad infinitum.

Running wpa_supplicant manually just generates an endless stream of stuff.

Any suggestions to help solve or isolate the problem? Curiously WPA worked on this exact hardware without any problem when I previously tried PCBSD 1.4 (FreeBSD 6.2, I believe).

Many thanks,

sim
