How to Enable IPv6 on Your Wi-Fi Router

Before you start

The fastest way to enable IPv6 is usually on the Internet or WAN page of your router admin interface. If the option is hidden, look for an advanced view or advanced setup section. Before changing anything, confirm that your internet service provider (ISP) actually delivers IPv6 to your connection. Some older plans still use only IPv4, and enabling IPv6 without ISP support can leave the router without an IPv6 address.

You do not need to remove IPv4 while enabling IPv6. Most routers run both protocols at the same time. Keeping IPv4 active ensures older devices and services continue to work while IPv6-capable devices can use IPv6 when available. For a quick overview of how IPv6 works on home networks, see IPv6 explained.

Check with your ISP if you are unsure whether your connection includes IPv6. The answer affects which connection type you should choose on the router.

• Admin access to the router, usually through the router app or web interface.
• Your ISP IPv6 connection type, if known.
• A device with IPv6 support to test the connection.

Find the IPv6 settings page

Start by logging in to the router as an administrator. The IPv6 settings are rarely on the first page. Look under WAN, Internet, Network, Advanced Setup, or simply IPv6, depending on the router. On many routers, the same page also has the WAN connection type, DNS, and MAC address clone settings. If you cannot find the IPv6 section, use the search box in the admin area if one exists. For login help, see how to log in to the router admin page.

Some routers manage IPv6 in the mobile app. The app may show only basic settings, while the web interface exposes the full IPv6 page. If the app does not show IPv6, try the web-based admin page.

Choose the correct IPv6 connection type

The right setting depends on how your ISP delivers IPv6. Many home ISPs use DHCPv6 or an automatic native IPv6 option. In that case, select DHCPv6, Native, or Dynamic IP and save. If your ISP uses PPPoE for internet access, choose PPPoE and enter the same username and password used on the IPv4 WAN page. See how to change the WAN connection type for the general steps.

ISPs sometimes call the option by different names. The behavior is the same: the router asks the ISP for an IPv6 prefix and uses it to assign addresses to devices on your LAN. If you have a modem from the ISP in bridge mode, your router may receive the public IPv6 connection directly. Bridge mode explained describes that setup.

Set the IPv6 options

After choosing the connection type, look for additional IPv6 options. Most routers ask how the LAN should get IPv6 addresses. SLAAC and DHCPv6 are common methods. Leave the default unless your ISP or network setup requires something else. The router will normally assign addresses automatically and also configure DNS. If your ISP gave you specific DNS servers, enter them; otherwise automatic DNS is usually fine.

Check whether the router requests a prefix from the ISP. Prefix delegation is useful for home networks that use multiple subnets or mesh nodes. If the router does not request a prefix, every LAN device might still get a global address, but advanced segmentation may be limited. A simple home network can usually leave this on the recommended setting.

Confirm your network receives a global address

Save the settings and wait for the router to reconnect. On the IPv6 status page, check that the WAN interface reports a global IPv6 address and prefix, not just a link-local address. A link-local address is only valid on the local segment and does not provide internet connectivity.

Then check a client device. A computer, phone, or tablet connected to the Wi-Fi should show an IPv6 address with the same prefix as the router LAN. If it shows no global IPv6 address, the router may not be delegating a prefix, or the ISP may not have assigned one. Some routers include a built-in IPv6 connectivity test; use it if available.

Troubleshoot and keep security enabled

If IPv6 is enabled but the status page shows no WAN address, try switching the connection type to another common option, reboot the router, and check again. Some ISPs require the modem to be rebooted too. If none of the options work, the ISP may not offer IPv6, or the modem may be blocking it. Contact the ISP or look for a router setting that passes IPv6 through the modem.

Enabling IPv6 does not remove the need for a firewall. IPv6 networks generally do not hide every device behind a single address the way many IPv4 home networks use NAT, so keep the router firewall enabled and use current Wi-Fi security. Modern Wi-Fi certification includes WPA3 and Protected Management Frames, as described by the Wi-Fi Alliance security materials. For practical steps, see WPA3 explained, how to enable WPA3 on router, and router security basics.

When to leave IPv6 off

If your ISP does not offer IPv6 and you do not need it for a specific service, leaving it disabled is acceptable. Enabling it without a WAN address can create confusing status messages, though it should not break IPv4 internet access.

If you need IPv6 for a home lab or remote access, a tunnel service is an option, but it adds complexity. Focus first on a stable IPv4 connection and then add IPv6 when your ISP supports it.

Questions

Does enabling IPv6 make my Wi-Fi faster?

Not by itself. Wi-Fi speed is determined by the router radios, bands, and the client device. IPv6 can help your network reach IPv6-only destinations, but it is not a speed boost. See Wi-Fi 6 explained for what affects performance.

What if my router does not have an IPv6 page?

Update the firmware first. Some routers add IPv6 options in later firmware releases. If the router is very old, a model with IPv6 support may be necessary. See router firmware updates explained and the best Wi-Fi 6 routers guide.

Should I disable IPv4 after enabling IPv6?

Usually no. Most home networks need IPv4 for older devices, printers, and websites that have not adopted IPv6. Keep both enabled.

What is the difference between DHCPv6 and SLAAC?

Both assign IPv6 addresses. DHCPv6 can hand out additional settings such as DNS servers, while SLAAC lets devices configure an address from router announcements. The right choice depends on your router and ISP.

Is IPv6 more secure than IPv4?

Security depends on configuration. Keep the router firewall enabled and use current Wi-Fi security such as WPA3. See router security basics for more.
