# 把树梅派配置为无线路由器
首先需要一个受驱动支持的无线网卡，配置的结果就是把树梅派的网络连接通过无线网卡分享出来。做分享的无线网卡当然就不能同时来连接网络了。
安装hostapd
1. sudo apt-get install hostapd
*复制代码*
配置hostapd.conf
1. interface=wlan0
2. driver=nl80211
3. ssid=网络名称
4. channel=6
5. hw\_mode=g
6. wpa=2
7. wpa\_passphrase=密码
8. wpa\_key\_mgmt=WPA-PSK
9. wpa\_pairwise=TKIP
10. rsn\_pairwise=CCMP
*复制代码*
安装isc-dhcp-server
1. sudo apt-get install isc-dhcp-server
*复制代码*
配置/etc/dhcp/dhcpd.conf，在末尾添加
1. subnet 192.168.111.0 netmask 255.255.255.0 {
2. range 192.168.111.50 192.168.111.150;
3. option routers 192.168.111.1;
4. option domain-name-servers 8.8.8.8;
5. option ip-forwarding off;
6. option broadcast-address 192.168.111.255;
7. }
*复制代码*
启动hostapd
1. sudo hostapd hostapd.conf -B
*复制代码*
设置无线网卡地址
1. ifconfig wlan0 192.168.111.1
*复制代码*
启动isc-dhcp-server
1. /etc/init.d/isc-dhcp-server start
*复制代码*
配置iptables
1. echo 1 > /proc/sys/net/ipv4/ip\_forward
2. iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
*复制代码*
这样就可以把树梅派的的有线网络连接通过无线网卡信号分享出去，可以用手机或平板测试一下。如果对iptables足够了解还可以配置很多高级内容。树梅派仅仅配置成为一个无线路由可能还不够，可以配合文件服务器一起用。并不是所有网卡都能配置成功，下面是简单测试结果：

关于传输速度方面也可以做更多的测试。
