Thanks. I'm not sure why you'd get the warning there every few seconds, but I suppose we don't really care all that much. I think you're probably running afoul of a bugfix that I did while at the wireless summit, and then the fix to it made it in, but not yet the fix to the fix :( Are you using an encrypted network, or an open one? If it's open, can you try this patch? http://johannes.sipsolutions.net/patches/kernel/all/2009-09-24-17%3a32/010-= cfg80211-fix-wpas-open.patch johannes --=-zQP4/TBq1gZ1kWjoca51 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJKu63oAAoJEODzc/N7+QmanAUP/0WuwyDQX6WwvumXRbiGOSx6 3k2erulOYw1m/O6FdWOP/oUgNaTdkYZ/gptpfmvyfMXOCCFGWB0O2QGBN8Od7IqX h8VUm/0M+FESOE7SjvnAJMAKYVUMlaEymvxvjgisrv1QJGmlCR03CBvWnwhgVFTU J1oPXxqLRRNp0Ig63bfDi2/Fq5psazbhd+/8M7T2T++P3OwltybzvbOD6sdN0iyQ sVPzenOYhTQmCVhNmyVPWyTYCUEvLFGTQDJVR/VnoMEkgJJtUvkhNILVbmkLNvV3 kaniwx6HMRNjZVQoagknuntAhVjqkgBYpns6ZhwQ4RxU/eCTypfeldfzJbAhPSi8 BUt2oc9YLehTcFY6QHB8zgMjLqdO5JHxBtatG0PQ5ltz82NH1RXcdN2zQMqfrKka GHkRLYdQ2lD9ClQsGZYPxHBoAQT/j+i8MKzr7g4DnbVCKOeeoCHRxTWT484vJr4e kPWSTon+1Lj8LZUbEIdBuLlbCm+bA320Kwz155H8hPSzZc4aOKox3+lkKtmJinjG dRGwQd0NlrDjuXCchEVxr1LPwlaM68gDvHkeOFTrurMSAkQ/BTzWwty+rP6ql3Ay v+vaR53PhmVb+5oal7Dol7Ga/EeKa9KUNHJcS/dX1owUBG+ClaypNda8UsC1lvlB NjbLyNKggQqegWh5WGP3 =h9zM -----END PGP SIGNATURE----- --=-zQP4/TBq1gZ1kWjoca51--
