I'm not sure about this specific issue, but if you feel like using out-of-tree patches that are never likely to make it upstream, you can find patches in our tree that disables the Intel firmware's beacon filtering (and beacon RSSI reporting) and then does the RSSI calculation in the driver. It is not a small change and might have some weird dependencies on other stuff in our tree. That fixed some inaccuracies that we found, but it may have draw-backs that I'm not aware of. https://github.com/greearb/linux-ct-6.13 Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
