IPv6 not available on Connect Box 3 Fiber

Zephon

I have Up Connect L with a Connect Box 3 Fiber. I noticed that my wife’s Iphone would load really slowly. And my Samsung Smart TV does connect to the WiFi but fails to connect to the internet. After some troubleshooting and searching I found an entry in the router status network log that says “erouter0 ipv6 address is empty”. I called customer support and they told me that IPv6 is just not activated. He did activate it and my TV finally connected. But when I tried again a few hours later, it didn’t work again. And when I checked the logs again, it gave the same error message “erouter0 ipv6 address is empty”. So I called again and told them about my issue. After some initial confusion I was told that the Connect Box 3 Fiber simply does not support IPv6 and nothing could be done about it. Which is crazy to me, since some devices force IPv6 very aggressively. After some research I found out that I am probably not the only one with this issue. So I would like to kindly ask for your help in this case.

hello Zephon

Welcome to the community.

It’s true, you’re not the only one with the IPv6 error. The FIBRE box can run on IPv6 with DS-lite. But if your connection is set to run on IPv4 only you won’t get an IPv6 address.

There’s another issue going on with the Connect Box 3 FIBRE. This issue is not related to IPv6 but to connection loss and devices unable to connect to the internet. Please try to disable the WiFi channel optimization.

Let us know, if this fixed your connection issues.

Your suggestion to disable channel optimization worked! My TV finally connects again and my wife’s Iphone is much more nimble when using Youtube, Instagram, etc. Thank you!

Zephon You can re-enable Wi-Fi optimization now that we’ve fixed the issue. Without Wi-Fi optimization, your Wi-Fi connection may become unstable.

Whatever you did (new router firmware..?) caused the error messages, which appeared in a 15min interval, to cease. I just turned channel optimization back on. Everything seems to be working as it should. Thank you very much!

Sunrise told me that IPv6 was not supported at all on the Connect Box 3. In the first days we had it, I saw a connection a couple of times that did not work but I’ve not seen any connection at all since.

Our DSL box had IPv6, I’m struggling to understand what they’re saying or why this apparently OK.
