Such as : * 5200 MHz [40] (17.0 dBm) (passive scanning, no IBSS) The channel 40, 5200 MHz, the max power is 17, you would not have a chance to change it over 17 dBm. Does it answer your question ? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
