如何在Debian上设置接入点（WiFi热点）

我正在尝试设置AP卡住。我正在使用Odroid U3，而WiFi适配器是Hardkernel 的Module 3。我也在用Debian Jessie。

不能，我几乎可以正常工作：Odroid可以访问互联网，并且其他设备（我的手机和平板电脑）可以看到网络，但是当我尝试连接到网络时，却收到消息：无法加入网络“ myNetwork”。

我的主机文件如下：

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

auto lo br0
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet manual

allow-hotplug wlan0
iface wlan0 inet manual

# Bridge setup

# for dhcp address
#iface br0 inet dhcp
# bridge_ports eth0 wlan0

# for static ip
iface br0 inet static
bridge_ports eth0 wlan0
# adapt with your network settings
address 192.168.1.250
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 192.168.1.1
fns-search localdomain

我的hostapd.conf文件是：

    interface=wlan0
driver=nl80211
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
ssid=RaspAP
hw_mode=g
wpa=2
channel=8
wpa_passphrase=raspiwlan
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
rsn_pairwise=CCMP
beacon_int=100
auth_algs=3
wmm_enabled=1

并且ifconfig的结果是：

经过一番研究，我找到了一个关于SO的答案（不幸的是丢失了链接），该答案表明问题可能与连接到Odroid的设备的动态IP地址有关，但我不确定是这种情况。有什么建议？

非常感谢

以下是用于创建WiFi AP的脚本：

• SetupWiFi.sh-设置WiFi网络并与wlan0共享eth0。更改“ ssid”和“ wpa_passphrase”以设置WiFi SSID（AP名称）和密码。
• StartWifi.sh-启动WiFi。（SetupWiFi.sh已经启动它，因此您可以第一次跳过它。）
• StopWiFi.sh -停下来

SetupWiFi.sh：

#!/bin/bash
apt-get install -y hostapd dnsmasq wireless-tools iw wvdial

sed -i 's#^DAEMON_CONF=.*#DAEMON_CONF=/etc/hostapd/hostapd.conf#' /etc/init.d/hostapd

cat <<EOF > /etc/dnsmasq.conf

wpa_passphrase=YOUR_PASSWORD
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
# Change the broadcasted/multicasted keys after this many seconds.
wpa_group_rekey=600
# Change the master key after this many seconds. Master key is used as a basis
wpa_gmk_rekey=86400

EOF

service hostapd start

StartWiFi.sh：

#!/bin/bash
service hostapd start
service dnsmasq start

StopWiFi.sh：

#!/bin/bash
service hostapd stop
service dnsmasq stop

笔记：

• 在Debian 7上进行了测试，但应该在更新的版本上工作。
• 确保您正在运行超级用户。（对于新手）通过使用以下命令使这些文件可执行chmod +x 'SetupWiFi.sh'

希望能帮助到你。
