Any Raspberry Pi, model B with power supply.

This project configures your Raspberry Pi to connect to the Internet through ethernet, and share that connection over WiFi.

6.2 5 GHz ieee80211ac example configuration.

6.1 2.4 GHz ieee80211n example configuration.Now open DHCPCD config file sudo nano /etc/dhcpcd. Restore network interface sudo nano /etc/network/interfaces

Save, exit and run: sudo sh reset_firewall.sh # Failsafe - die if /sbin/iptables not found Write script to restore default iptable nano reset_firewall.sh Restore original network settings sudo nano /etc/nf Uninstalling Dnsmasq: systemctl stop dnsmasq Please remember this is not a continuation of the tutorial. In case you don’t need this anymore and want to delete all changes we made, please follow these steps. If you got this right, you should have internet. Open your internet browser and check some websites. On my computer I’m getting IP address starting from 192.168.5… To check on windows 10, run command and type ipconfig. You computer should get IP address distributed in your ethernet interface. Plug the ethernet cable on your computer and the other end to your raspberry pi. To test if it works, turn off your computer’s wifi. Paste this on top of exit 0 iptables-restore < /etc/ Save the changes sudo sh -c 'iptables-save > /etc/' Sudo iptables -A FORWARD -i eth0 -o wlan0 -j ACCEPT Sudo iptables -A FORWARD -i wlan0 -o eth0 -m state -state RELATED,ESTABLISHED -j ACCEPT Uncommend this line by removing # character: _forward=1 sudo sh -c 'echo 1 > /proc/sys/net/ipv4/ip_forward'Ĭhange iptables sudo iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE To share Raspberry Pi internet from wifi, we have to configure ipv4 forward and set iptables routing connection from wlan0 to eth0. Start the service systemctl start dnsmasq SHARING INTERNET FROM WIFI AND SHARE TO LAN To configure, stop the service first systemctl stop dnsmasqīackup the default configuration: sudo mv /etc/nf /etc/ĭhcp-range=192.168.5.50,192.168.5.100,12h We’ll choose Dnsmasq application sudo apt install dnsmasq Wpa-conf /etc/wpa_supplicant/wpa_nfĮnable networking service sudo systemctl enable networkingĭeny interfaces on dhcpcd denyinterfaces eth0 Now that we are sure we are connected on wifi and with static ip configured, we can now start to change from DHCP to NETWORKING static ip address method. To check where the wifi ssid and password is saved: sudo nano /etc/wpa_supplicant/wpa_nf SET STATIC IP ADDRESS Here’s my configuration sudo nano /etc/nf I’m having static ip address using DHCPCD method. Let’s begin by connecting on Raspberry Pi wifi and update the system. You may check my tutorial about how to install Raspberry PI OS Lite and setup static Ip address.
