Tags: #IPv6
Model: Deco X50-4G  
Hardware Version: V2
Firmware Version: 1.1.2 Build 20240806 Rel. 45245

I get the below errors and notices repeatedly, any ideas? Should I just ignore them? 
My deco is on 3G/4G Router mode.

Thanks and regards

Hi,

While IPv6 itself doesn't inherently cause devices or apps to function slower, certain compatibility issues or misconfigurations can lead to performance problems. 

May I know your SIM carrier provider?

Some mobile service providers might use 464XLAT, and Deco hasn't added this feature yet. In this situation, when enabling IPV6, certain websites might fail to load.

such as 464XLAT Support on TP-Link 4G/5G routers for Jio/EE/Optus/Vodafone and other SIM carriers

Thank you very much.

Best regards.

Hi, thank you very much for the feedback.

Have you noticed any network issues with IPv6 connection?

 

Based on the current logs, it is not enough to say what had happened.

The following log seems to imply IPV6 disconnection, but it only lasts 1s

Tue May 20 13:36:06 2025 daemon.notice netifd: interface_proto_cb Interface 'wanbv6' is now down.

 

If all devices are working properly, I think there is no need to worry much about these logs.

Best regards.

Hi, My devices seem to function, but I don't know if need ipv6 or not. Can some of the devices or apps be functioning slower because of it? Thanks Hakki

  @David-TP Thanks for the feedback. My provider is Turkey, turktelekom. Apparently it does not support ipv6 in my area at all. Regards
