Re: [Madwifi-users] Unable to set Distance up to 27000

[Michael P. <mpl...@di...>]

The limited value seems to be related to the frequency. Using another
 frequency allow me to use greater distance up to 58000 meters.

 Problem solve ! Thanks

 By the way is there a way to use madwifi driver for big distance like 60 km
!

 I got big antenna and great signal (28 rssi), but poor speed (less than 100
 kB/s) probably related to slottime parameter.

Someone have a solution or an idea,
