The Realtek group made several changes in the driver that Chaoming sent you that have not yet been incorporated in the kernel version. If you test that driver, we might learn if any of them are important to your problem. As neither of us can duplicate your results, it is not possible for us to do those tests. I agree that we want to fix the kernel version. It is unfortunate that Realtek does not generate their improvements as patches to that kernel version, and publish them that way, but that is a fact of life. When they produce a new version, I have to look at the diff file between it and the previous version and test those differences with my devices. Thus far, there have been no changes that have any effect on my system, but who knows on yours. Please run the test as Chaoming asked you to do. Thanks, Larry
