false/ridiculous Qualitiy values with "iwlist athX scan"

Reported by: Assigned to:
Priority: minor Milestone:
Component: madwifi: other Version: v0.9.3.3
Keywords: Cc:
Patch is attached: 0 Pending:



I'm using madwifi stable on a 2.6.27-7 kernel with a voyage-image on a wrap board with wistron cm9 cards. When I try to scan how many other accesspoints are in my area, I get some crazy quality-values like 214/70. Strong accesspoints are shown correct, but weak APs are always shown with far too high values. But these values are fluctuating from the real quality-value (like Quality=10/70) to these abnormal high values. The same problem appears on the same hardware with an older 20.99 revcount madwifi.

I hope you can help us.
