How to Fix Error Code 13
-
Restart Your Router and Modem
Do not skip the full 60-second wait. Rushing the reboot cycle often means the ISP does not re-issue a fresh prefix. -
Confirm Your ISP Supports IPv6
-
Log Into the TP-Link Admin Panel and Check IPv6 Settings
Do not change settings you are unsure about without first noting your current values so you can restore them if needed. -
Set the Correct IPv6 Connection Type
-
Disable IPv6 If Your ISP Does Not Support It
-
Update the TP-Link Router Firmware
Never power off the router during a firmware update. A failed update can make the router unresponsive and may require a factory reset or professional recovery. -
Perform a Factory Reset as a Last Resort
A factory reset erases all saved settings including custom Wi-Fi passwords, port forwarding rules, and parental controls. Write down your current settings before proceeding.

When to Call a Professional
Contact your ISP's technical support if you have confirmed IPv6 is included in your plan but Error Code 13 persists after all steps above — the problem may be a misconfiguration on the ISP's infrastructure side, such as a failed DHCPv6-PD lease or an incorrect prefix pool assignment on their equipment. Additionally, if your TP-Link router becomes unresponsive after a firmware update or factory reset, contact TP-Link support (1-866-225-8139) or a local networking technician for recovery assistance.Frequently Asked Questions
What does TP-Link Error Code 13 mean?
Error Code 13 on a TP-Link router means the router attempted to obtain an IPv6 address prefix from your ISP but did not receive one. This prevents your network devices from being assigned valid IPv6 addresses. It is usually caused by an ISP that does not support IPv6, a mismatched IPv6 connection type in the router settings, or a temporary provisioning issue on the ISP's network.
Will Error Code 13 break my internet connection?
Not necessarily. If your ISP and router are both working correctly on IPv4, your regular internet browsing, streaming, and gaming will continue unaffected. Error Code 13 only affects IPv6 connectivity. However, some services and websites are beginning to prefer IPv6, so resolving the error is still worthwhile for future compatibility.
How do I know if my ISP supports IPv6?
The easiest way is to call your ISP and ask directly whether your account plan includes IPv6 with Prefix Delegation (DHCPv6-PD). You can also visit a site like test-ipv6.com from a device connected to your TP-Link router — if it shows a failing IPv6 test, your ISP may not be providing it. Many budget and rural ISPs still only offer IPv4.
Can I just disable IPv6 on my TP-Link router to fix Error Code 13?
Yes, disabling IPv6 in Advanced > IPv6 on your TP-Link admin panel is a completely valid fix if your ISP does not support IPv6 or if you do not need it. Your internet connection will continue operating normally over IPv4. Error Code 13 will stop appearing because the router will no longer attempt to request an IPv6 prefix.
Why did Error Code 13 suddenly appear when it was working before?
A few things can cause this to appear suddenly: your ISP may have changed their IPv6 provisioning system, a firmware update on the router may have reset the IPv6 configuration, your ISP's DHCPv6 server may have had a temporary outage, or your IPv6 lease may have expired and renewal failed. Start by rebooting your modem and router (Step 1), which resolves the majority of sudden Error 13 occurrences.
