Thanks for your reply.
I don't need Mesh feature, but for some reason I can't upgrade my kernel to 2.6.34 (Most of my driver will be re-written).
But I managed to upgrade to 2.6.32, but the problem is still there.

I am wondering if there is some defects(bugs) in my SDIO driver?
My problem is: I can use 'iwlist eth0 scan' to get AP list, but association failed. If SDIO issue then why just 'iwlist eth0 scan' can work?
