Problem with s23 in ipv6 wifi but ok in ipv4 &4G

[Members_aqzCRdz]

With my S23 I use wifi (not wifi6) some applications like sonos or spotify begin to slow and hang during network access .
- some other apps go on to work well.
- the apps thar are not working well  with the S23 are working well in wifi with other phones...
-on the S23 when I stop the wifi, all apps work well back with the 4G....

I tried a lot of things (dynamic iP,/static IP , randomized MACs or not, reinstall apps , wipe apps cache and data ) with no success.

The workaround I found was to stop IPV6 on my internet box . On the samsung S23 all works fine in IPV4. But this solution is not very satisfactory.

Hey there

I've seen some reports that individual networks have been having some issues with IPv4 and IPv6 conversion.

This has impacted users. I've definitely seen something about Vodafone on this although I did think it was recently resolved.

I suspect it isn't your device as such, more likely to be your network / WiFi provider but calling Customer Services to get answers on this will likely result in you losing the will to live (most customer service agents won't have a clue on this and you'll need either 2nd line tech support or even 3rd line back office ((we don't speak to customers)) support).

Mhm, I use ipv6 and it's sweet. Same device.

As above, it's the router or isp.

Lots of public WiFi is now ipv6 so you have probably enjoyed using it without knowing.
