The address looks OK to me. I do not know why it bounced. My involvement with the RTL8187 devices only started with 2.6.X, where X is 25 or 26. I have no knowledge of the driver in kernel 2.4. There have been various complaints about the driver, particularly on RTL8187L hardware, that concern rate setting using the minstrel algorithm. I have been unable to reproduce the results. Please answer the following questions; Does the device work is you lock the rate at 1 Mbps? What is the USB ID as shown by lsusb? Does it work when you use the PID rate-setting algorithm? To enable this, you will need to set CONFIG_EXPERT=y. Larry Does it work better if you choose
