How to configure IPv6 for wireless network on Ubuntu?

@aliya.yundt 

To configure IPv6 for a wireless network on Ubuntu, follow these steps:

1. Open the terminal on your Ubuntu system.
2. Type the following command to open the network configuration file:

1

sudo nano /etc/network/interfaces

1. Add the following lines to the file, replacing "wlan0" with the name of your wireless interface:

1
2

auto wlan0
iface wlan0 inet6 auto

1. Save the file by pressing Ctrl+O and exit nano by pressing Ctrl+X.
2. Restart the networking service by typing the following command:

1

sudo service networking restart

1. Verify that your wireless network interface has an IPv6 address by typing the following command:

1

ifconfig wlan0

1. You should see an IPv6 address listed under the "inet6" section for the wlan0 interface.

Note: If your wireless network is using a static IPv6 address, you can replace "auto" with "static" and add the IPv6 address to the configuration file. For example:

1
2
3
4
5

auto wlan0
iface wlan0 inet6 static
  address 2001:db8::2
  netmask 64
  gateway 2001:db8::1

This configuration assumes that your wireless network is configured to support IPv6. If your network does not support IPv6, you may need to contact your network administrator or service provider for assistance.

Additional Steps for network-manager

If you are using network-manager to manage your network interfaces on Ubuntu, you can configure IPv6 for your wireless network using the following steps:

1. Open the terminal on your Ubuntu system.
2. Type the following command to open the network connections settings:

1

nm-connection-editor

1. Select the wireless connection you want to configure for IPv6 and click on the "Edit" button.
2. In the connection settings window, go to the "IPv6 Settings" tab.
3. Select the dropdown menu next to "Method" and choose the appropriate IPv6 configuration method (e.g., "Automatic," "Manual," etc.).
4. If you select "Manual," you will need to enter the IPv6 address, prefix, gateway, and DNS servers manually.
5. Save the changes and close the network connections settings window.
6. To apply the changes, you can either restart the network-manager service or simply reconnect to the wireless network.
7. You can verify that your wireless network interface has an IPv6 address by using the following command:

1

ifconfig wlan0

Keep in mind that network-manager provides a graphical interface to manage network connections, making it easier to configure network settings, including IPv6, for wireless networks on Ubuntu.
