To clarify the situation.
I have two routers, the provider router and a private router (with openwrt).
The private router is connected behind the provider router
The ipv6 was working well. I had just to give the public prefix to the router wan6 configuration.
Nevertheless, I have recently moved.
Even if the provider router is physically the same after the move its ipv6 prefix changed.
The old public prefix was still configured in my private router.
The situation was very strange. On Ip attribution for my computers, I still get a ipv6 address with an old prefix. dns was resolving in ipv6 but no working ipv6 connection.
Most programs were falling back to ipv4. So I only notice the problem after two weeks and it took me two more days to understand what was happening.
That's said the ipv6 is not the problem and effectively none of the network stack of the raspiOS should be modified.
BUT having a connection timeout on wget seems to be a good policy for whatever problem there is on the network. For this ipv6 problem or another.
The aim of my post was this.
