To create a wireless bridge on Ubuntu, you can use the following steps:

  1. Check your wireless interface name:
1
sudo iwconfig


  1. Disable network-manager:
1
sudo service network-manager stop


  1. Edit /etc/network/interfaces to add the bridge configuration:
1
sudo nano /etc/network/interfaces


Add the following lines at the end of the file:

1
2
3
4
5
auto br0
iface br0 inet dhcp
bridge_ports wlan0
bridge_stp off
bridge_fd 0


In this example, wlan0 is the name of the wireless interface that will be bridged.

  1. Save and exit the file.
  2. Restart the networking service:
1
sudo service networking restart


  1. Configure the wireless interface to connect to the network you want to bridge:
1
2
sudo iwconfig wlan0 essid [network name]
sudo dhclient wlan0


Replace [network name] with the name of the network you want to connect to.

  1. Test the bridge by connecting a device to the Ethernet port of your Ubuntu machine. The device should be assigned an IP address from the network you bridged.


Note: This configuration is temporary and will be lost after reboot. To make the bridge configuration permanent, you need to add the configuration to /etc/rc.local or create a systemd unit file.

  3. Create a bridge interface by running the following command in the Terminal: sudo brctl addbr br0
  4. Add the wireless interface to the bridge by running the following command in the Terminal: sudo brctl addif br0
  5. Configure the IP address for the bridge interface by running the following command in the Terminal: sudo ifconfig br0
  6. Test the wireless bridge by connecting a device to the wireless network and ensuring that it can communicate with other devices on the network.


Note: These steps may vary depending on your specific network setup and configuration. It's recommended to consult the documentation of your router or network provider for any additional steps or settings that may be necessary.
