This behavior was mentioned in Herton's e-mail, and said to be likely due to recent rewrite of the rate-control api? I am still using the early incarnation of the rate-control patch with 2.6.26.7-86.fc9.x86_64 and 2.6.27.4-69.fc10.x86_64 (by rolling back wireless-testing to 2.6.27.x to match), and my rate does go up and down (between 11M to 36M just now) and generally feels more responsive. Apologies I haven't looked at the newly posted rate-control patch yet - is there any significant code difference? Hin-Tak Hin-Tak
