Okay. I think you are right. How would I include this version rather than the one that comes with the kernel I have. thanks -----Original Message----- From: Booi [mailto:L....@lb...] Sent: Monday, January 10, 2011 11:43 AM To: gum...@li... Subject: Re: [Gumstix-users] Need help: How to change wifistix txpower or tx range? It works fine for me. May be you can take a look at the source files and documentation from the link below as I also don't know how to resolve it. I guess might be the driver was not installed or configured properly? http://files.gumstix.com/cf8385-5.0.16.p0-26306.tbz Leif Zars wrote: > > iwpriv returns no private ioctals > how do i correct this > thanks >> >> Kernel version 2.6.21. >> >> >> sakoman wrote: >>> >>> On Fri, Jan 7, 2011 at 9:09 AM, Booi <L....@lb...> wrote: >>>> >>>> Finally, I managed to change the TX power successfully. :) >>>> >>>> We will need to disable the auto transmit power control and power >>>> adaptation >>>> of the interface to make it works.
