I am trying to run wireless video over our wireless link and with the Cisco 1200 running at 54Mbps vs. 11 mbps. The 11 out performs the 54mbps by a wide margin. The AP is running IOS 12.2(13)JA. I will try upgrading to JA4.
I think I've seen a bug similar to what you're describing. You might want to check the bug tool kit.
Is the AP set for "Throughput" or "Distance"(or Custom)?
What is the bit-rate of the video your are sending?
Are all of the visible clients running G, or is there a mix of B and G?
