我有一个 raspberry PI 2 并已将 HOSTAPD 和 udhcpd 配置为热点。我遇到的第一个问题是司机。我购买的 WiFi 适配器是 Realtek 芯片组。现在通过关注这篇文章解决了这个问题。 https://www.raspberrypi.org/forums/view ... hp?t=62371

现在我面临的第二个问题是 WPA2 身份验证。如果我将 hostapd 设置为 open\no 身份验证，它就像一个魅力。如果我设置身份验证，我将无法连接。Andriod 设备绕着连接转，iPhone 回来时密码不正确——即使我认为我输入了正确的密码。

以下是 hostapd.conf 中的配置和来自 hostapd --ddK /etc/hostapd/hostapd.conf 的日志

我没有看到提到的 DHCP 服务器 - 这是使用 hostapd 设置无线网络的关键基础设施。有关设置 DHCP 服务器的换行符下方提供了更多信息。不过，在介绍之前，这里有一些包含更多一般信息的链接。所有链接都指向charlesreid1.com/wiki。我用它们来记录我将 Raspberry Pi 设置为无线接入点的过程。所有页面均指使用 Raspberry Pi 创建 wifi 网络/接入点：

以下是有关设置 DHCP 服务器的一些信息，以防将 Raspberry Pi 设置为无线 AP 时出现问题。

通过编辑设置 DHCP 服务器/etc/dhcp/dhcp.conf。

首先，添加“权威”一词，表示这是网络上的权威DHCP。（您应该会看到一些注释和行已经填写在默认安装到 Raspberry Pi 上的 DHCP 配置文件中）：

  # If this DHCP server is the official DHCP server for the local
  # network, the authoritative directive should be uncommented.
  authoritative;

取消评论权威。

然后在 DHCP 配置文件中添加一个块来设置 IP 地址分配/配置。我在我的家庭网络上使用 IP 子网 192.168.42.X。

  subnet 192.168.42.0 netmask 255.255.255.0 {
    range 192.168.42.10 192.168.42.50;
    option broadcast-address 192.168.42.255;
    option routers 192.168.42.1;
    default-lease-time 600;
    max-lease-time 7200;
    option domain-name "local";
    option domain-name-servers 8.8.8.8, 8.8.4.4;
  }

您不需要所有这些选项，但请尝试一下。

接下来，您需要告诉 DHCP 服务器使用哪个接口，以便您可以编辑/etc/default/isc-dhcp-server和更新该INTERFACES部分以指向您的特定接口：

INTERFACES="wlan0"

现在您需要更新您的网络接口，以便它知道不要尝试寻找 IP 地址。把界面拉下来，

$ sudo ifdown wlan0

然后编辑/etc/network/interfaces并手动将 Pi 的 IP 地址指定为网关地址（我再次使用 192.168.42.X 架构，但您可以使用任何您想要的，只要它与上面提到的 DHCP 配置文件匹配）：

allow-hotplug wlan0

iface wlan0 inet static
    address 192.168.42.1
    netmask 255.255.255.0

最后一步是编辑您hostapd.conf已经完成的文件。这是启用 WPA2 后的样子（看起来您已经弄清楚了这部分并且可以正常工作）：

interface=wlan0
driver=<insert driver here>
ssid=<insert SSID here>
hw_mode=g
channel=6
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=<insert passphrase here>
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

希望这些信息中的一些有用......快乐的黑客！
