correctly.

It does not matter whether you have Windows, Linux or Solaris. Signal 
strength is independent of OS. What you see under Windows is a gimmick, 
ie, if there is a channel lock, show display bar > 80%. that's all in 
the strength inicator, even though under Linux, we don't have a 
graduated scale, to show the actual strength. Nothing to get upset.


I have not tried with 2.6.10, still on 2.6.9 due to certain 
development/fixing stage at the moment.
