Site survey shows all neighbors at 100%

This is new. I generally see 6 or 7 neighbors in the site survey on 2.4 GHz at varying signal strengths. Today, all of them show at 100% in both active and passive survey mode.

InSSIDer shows the neighbors at varying RSSIs, from -27 to -81. So I'm guessing the router's site survey is showing incorrect results.

Known issue with the wireless driver (which sometimes will incorrectly report all signal levels as being 100%). The issue is in the closed source driver, nothing that can be done about it. Usually, restarting the wireless interface resolves it.
