I have done so successfully = using Fedora 14 on identical hardware but I would greatly prefer to use = Gentoo so I can use a more recent kernel and customize things = appropriately for the platform. I have an up-to-date ~x86 Gentoo build working and I am able to run = hostapd as a 2.4GHz access point, but trying to run it on a 5 GHz = channel in "a" mode fails complaining it is unable to set the channel. = After some poking around I realized that this was due to the regulatory = domain not being set correctly--the default ("world"?) regdomain doesn't = allow IBSS on any 5GHz channels. I made sure I had crda emerged and tried several different kernel = settings but none of them resulted in any different behavior. I even = tried statically compiling the regdb = ("CONFIG_CFG80211_INTERNAL_REGDB=3Dy") but didn't see any difference. I = can run "iw reg set US" all day long but whenever I run "iw reg get" it = always comes back with "country 00" on the Gentoo system. Since I'm a relative newbie to both Gentoo and custom Linux kernel = building I wanted to make sure I wasn't just missing a setting or kernel = config flag somewhere before I started looking for things like driver = regressions. Can anyone suggest different things to try to fix the = problem or at least pinpoint it better? Below is some info from both the Gentoo system (regdomain not working) = and the Fedora system (regdomain working). Let me know what additional = information would be helpful. Thanks!
