So how > do I get it? First, make sure it's mounted, check "mount" and if not mount it: sudo mount -t debugfs debugfs /sys/kernel/debug If that doesn't work you don't have it enabled in the kernel config, check for CONFIG_DEBUG_FS. If you do have it, but not mac80211's files, check for CONFIG_MAC80211_DEBUGFS. Thanks, johannes
