Flapping? You need to provide more info than this.

Is the wireless SIGNAL going up/down or is the radio chipset going up/down?

Looks like its your broadcom card trying to figure out the modulation it will be using. There isn't really any configuration changes that you would need to do on the WLC since your data rates is flapping from 19-54. As long as everything is transperent to the user, there is nothing really wrong. The download or transfer looks like its fine, so really, no issue if you ask me... I never use the Windows utility to check my signal anyways:)

Thanks,

Scott
