@B_D,

In order to troubleshoot this issue, I would recommend first trying to reboot your network. Sometimes, devices can try to connect with old credentials and cause connectivity issues. It would be helpful to know if this issue is affecting all devices on your network, including both wired and wireless connections.

Additionally, it's important to confirm that you have configured the correct internet connection type in the Deco app. Some ISPs may require specific protocols or different credentials for IPv6 and IPv4. If this is the case, a toggle may need to be switched. Our FAQ on Configuring IPv6 on Deco may be helpful in this regard.

I would recommend looking at this FAQ we have on the topic: Configuring IPv6 on Deco to see if you had missed anything while setting it up.

  @B_D,

Who is your ISP? I would recommend getting in touch with them to see how they handle IPv6 traffic - that way you can make sure that these settings are correct and move on to other possibilities without it hanging over our heads.

I do also have to confirm that your modem from your ISP is not a gateway that is managing the IPv6 traffic and DHCP server, and is instead placed in bridge or passthrough mode. It would make sense that your deco is able to receive an address but the clients are unable.

Do you know if your devices are able to connect to the network and see each other? Or do they show in the list of connected clients from the deco app?

  @B_D, 

You did not provide your Hardware Version so I can't be positive, but I believe so, as I have not heard otherwise. You may actually be surprised to see how far back some of our firmware support will go for some models, such as the Deco M4. I even just posted beta M4 firmware that added new features. Even if a unit is not set to receive new features, which usually only happens many years after a release, it is not uncommon for our developers to push firmware updates to fix existing bugs or with security patches, it is just less likely to receive anything new.

 I do know that we are currently in a period of rapid development of firmware that includes new optimizations and features. These are still actively being developed and released with the goal of bringing the firmware to as many networks as possible. given that the X60 is such a popular choice, it may be that the firmware is still being developed, they are just waiting to release a stable version of it.

We should know a lot more about the updates and models in the coming months.

Also, the reason that I mention that you should still check with your ISP is that different manufacturers will handle the traffic differently, with many routers only working as a proxy for translating the IPv4 addresses to the IPv6 that your ISP can work with. Also, the two settings that you have selected are technically both auto-configuring options where a handshake will need to occur between your modem and router - while connections can work fine under those situations, it may still be the cause if the negotiation is not successful.
