我有一个运行嵌入式arm linux设备
kernel 2.6.39.4
hostapd 2.0
wl1271 and wl1271_sdio modules loaded (no compat drivers)
该设备是TiWi-R2 module from TI。 临时和基础设施模式工作，但当我尝试设置softap我遇到问题： 我通过将hostapd.conf的内容设置为：
来创建一个没有加密的工作站interface=wlan0
driver=nl80211
channel=1
hw_mode=g
ssid=mya
正在引导的固件：
[ 6486.330000] wl1271: wlan power up
[ 6486.660000] booting firmware ti-connectivity/wl1271-fw-ap.bin
[ 6486.810000] wl1271: firmware booted (Rev 6.2.1.0.54)
SSID正在广播，其他设备可以看到但无法关联。在Ubuntu笔记本电脑上，尝试连接失败后，我从dmesg获得以下内容：
[ 548.289020] wlan0: authenticate with 00:xx:yy:zz:ww:qq
[ 548.300588] wlan0: send auth to 00:xx:yy:zz:ww:qq (try 1/3)
[ 548.504059] wlan0: send auth to 00:xx:yy:zz:ww:qq (try 2/3)
[ 548.708059] wlan0: send auth to 00:xx:yy:zz:ww:qq (try 3/3)
[ 548.912056] wlan0: authentication with 00:xx:yy:zz:ww:qq timed out
无法关联后，笔记本电脑将连接到另一个先前配置的接入点。在嵌入式设备上使用-dd选项启动hostapd，我可以得到一些调试消息，但我不太了解它们。这是笔记本电脑连接时hostapd端的输出：

过了一段时间，系统似乎因为不活动而解除了笔记本电脑的关联：

我在bugzilla看到了一个类似的帖子，但帖子很旧，属于wpa_supplicant（版本0.6.0），笔记本电脑上有wpa_supplicant 1.0的Ubuntu 13.04。这让我觉得hostapd不会通知客户该关联是否成功。
我也无法从任何其他设备连接到softap。我试过Android 4.4和iOS 7.0.4
我也尝试了wpa2配置和标准打开configuration files from TI，但没有任何效果。
修改： 我不知道我会把整个社区都归咎于这个......我已经升级到TiWi-BLE模块，TiWi-R2的官方继任者，但还没有成功。
我发现一个帖子有同样的问题，但没有解决方案here。
修改： 我通过使用内核3.12.0解决了这个问题，但没有出现此问题。在我看来问题就在于内核。我会暂时不回答这个问题，万一有人可以帮忙看看。
答案 0 :(得分：0)
我切换到了更新的内核。当时它是3.13.0-next，一个没有官方发布的内核，但由于它完美运行，我保留了它。
