Is a firmware update a possibility? We've had these discussions before. I doubt Sony is any more excited about a firmware spin than Intel has been. Does this problem apply to probe responses as well? (Do probe responses from hidden SSID APs still exclude the SSID? I would guess not.) As long as you can still associate w/ hidden SSID APs, I don't see a big problem. Even if you can't, no information for those APs is probably better than bad information, no? John -- John W.
