Thanks Steve! I have been using your 2.6.33 kernel. So far it completely fixes the speed and reliability problems I was experiencing with the onboard Fire wifi. I am able to get better than 10 Mb/s transfer rates using the ttcp socket benchmarking tool. This is essentially the same performance I see from laptops and desktops running the same test. Also, I have been able to get reliable lower rate streaming (<1 Mb/s) for long periods of time (24+ hours). The only problem I have seen in the update has been referenced in the thread already. I get a kernel oops when I unload the ads7846 touch screen module. Thanks again. This really improves the quality of the Fire system.
