Editor to share with you how to configure raspberry pie into a wireless AP, I believe most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's learn about it!

Hardware configuration

Raspberry pie RaspberryPI 2 Model B

USB Wifi

I bought USB Wifi specific information is IDEMAC SL-1506N wireless usb network card rt5370 chip 11n network card receiver AP, for reference. There are many on Taobao.

Install the necessary programs

Mainly includes hostapd,dnsmasq

Basic configuration

First plug in the USB Wifi

You need to start NAT in the kernel first.

Sudo iptables-t nat-A POSTROUTING-o eth0-j MASQUERADEsudo iptables-A FORWARD-I eth0-o wlan0-m state-- state RELATED,ESTABLISHED-j ACCEPTsudo iptables-A FORWARD-I wlan0-o eth0-j ACCEPT

Save the configuration of iptables

Sudo sh-c "iptables-save > / etc/iptables.ipv4.nat"

Edit configuration file / etc/network/interfaces

If the following exists, comment it out, like this

# auto wlan0#iface wlan0 inet manual#wpa-conf / etc/wpa_supplicant/wpa_supplicant.conf

Add the following at the end of the file

Allow-hotplug wlan0iface wlan0 inet static address 192.168.10.1 netmask 255.255.255.0 up iptables-restore < / etc/iptables.ipv4.nat

Modify / etc/default/ifplugd into

INTERFACES= "eth0" HOTPLUG_INTERFACES= "eth0" ARGS= "- Q-f-U0-D10-w-I" SUSPEND_ACTION= "stop"

Execute sudo ifup wlan0 to make the configuration effective

Modify / etc/sysctl.conf to make sure it contains

Net.ipv4.ip_forward = 1

Perform sudo sysctl-p to reload the configuration

Install and configure hostapdsudo apt-get install hostapd

Create the file / etc/hostapd/hostapd.conf and fill in the content

Interface=wlan0driver=nl80211ssid=MyPIhw_mode=gchannel=6macaddr_acl=0auth_algs=1ignore_broadcast_ssid=0wpa=2wpa_passphrase=12345678wpa_key_mgmt=WPA-PSKwpa_pairwise=TKIPrsn_pairwise=CCMP

Ssid and wpa_passphrase are modifiable. (I've tried the configuration without a password, but I don't have access to the Internet.)

Open the file / etc/default/hostapd and set the

# DAEMON_CONF= ""

Modify to

DAEMON_CONF= "/ etc/hostapd/hostapd.conf"

Run sudo service hostapd start and restart the hostapd service

Install dnsmasqsudo apt-get install dnsmasq

Open the configuration file / etc/dnsmasq.conf and add it directly at the end

No-resolvlisten-address=192.168.10.1interface=wlan0dhcp-range=192.168.10.100192.168.10.200,12hdhcp-option=option:router,192.168.10.1server=114.114.114.114server=8.8.8.8server=8.8.4.4

After saving, restart the dnsmasq service
