Model: Archer AX55  
Hardware Version: V1
Firmware Version: 1.3.5 Build 20241211 rel.34816

■ Status

TP-Link Archer AX55 v1

1.3.5 Build 20241211 rel.34816

IPv4 over IPv6（MAP-E）

IPv6 Internet Connection Type:Dynamic IP（SLAAC/DHCPv6）

Get IPv6 Address:Auto

Prefix Delegation:Disable

DNS Address:Get Dynamically from ISP

IPv6 Assigned Type：ND Proxy

 

■ Issue Encountered

IPv6 connectivity is not working.

Immediately after the router starts, IPv6 communication works normally, but within a few minutes, IPv6 communication from the devices becomes unavailable.

The issue seems to have started around the day a firmware update was applied last week.

Additionally, the client devices appear to recognize both an IPv6 address and IPv6 DNS.

The issue occurs on multiple Android devices.

 

■ Actions Taken

Rebooted the router, rebooted the ONU, and performed a factory reset of the router, but the problem was not resolved.

 

■ Checks and Verification Results

According to the router's logs, RA transmissions from the router are continuing. However, the MTU is being sent as <null>.

 

Please advise on how to resolve this issue

Hello@jp-user ,

Welcome to our community.

 

May I know the Internet service provider of your network?

Please enable 'Prefix Delegation', and disable 'ND Proxy' for a try.

Thank you for your reply.

I need to choose one of the following options when disabling the ND proxy.

Which one should I select?

 

 DHCPv6

 SLAAC+stateless DHCP 

 SLAAC+RDNSS

Hi@jp-user ,

Thanks for getting back to me.

 

Please select 'SLAAC+stateless DHCP' for LAN.

 

For WAN IPv6 addresses, try each one individually:SLAAC,DHCPv6,Non-address

Thank you for your advice.

Unfortunately, with either variation, the internet completely stopped working.

Thank you for your reply.

I was also in contact with the Japanese TP-Link email support, and they suggested the device might be faulty. Unfortunately, the warranty period had expired just a little over six months ago.

Because of this, I've decided to purchase a new AX80.

I'm disappointed because I had hoped to use the old one for much longer, but it can't be helped.
