我正在尝试在 Debian 系统上使用 Raling RT5370 USB Dongle 设置接入点，我遵循以下步骤教程，直到“互联网连接共享。”，我不想共享互联网，所以我跳过这一步。重新启动后，我可以看到 AP，但无法连接，似乎无法获取 IP 地址，如何在树莓派上调试以查看发生了什么或我在哪里犯了错误？
这是我的 dhcpd.conf 文件内容：
ddns-update-style none;
subnet 10.10.0.0 netmask 255.255.255.0 {
range 10.10.0.2 10.10.0.16;
option domain-name-servers 8.8.4.4, 208.67.222.222;
option routers 10.10.0.1;
}

我是否需要设置其他内容，因为我可以看到 AP，但无法连接。我刚刚在 Ubuntu 12.04 上测试并且它可以工作，我在 Raspberry Pi 上做了相同的配置，但没有成功
