Internet unstable after recent update

[manuel]

Haven’t checked the LTS kernel code, but here it seems to work too.

@UncleSpellbinder did on all three of your installed base with Linux Mainline kernel 6.16.5, with IPV4 enabled, was the issue resolved?

All I can say is that I’m not having any internet connection issues. I wasn’t one of the people messing with IPV4/IPV6 settings. Just out-of-the-box connection issues are perfect in my case.

Very glad this is sorted.

Thanks for being so helpful in this thread, @albersc2. Wish I’d had the time to try out your guide – but will bookmark it for some other time.

@Archie1

Has this issue been resolved in the Linux LTS Kernel 6.12.45-1?

Yes, I just downloaded the source for 6.12.45 and all the fixes and improvements, both Oscar Maes’ and the others, have been applied. Here’s an excerpt from linux/src/linux-6.12.45/net/ipv4/route.c, where you can clearly see Oscar’s fix:

if (ipv4_is_lbcast(fl4->daddr)) {
	type = RTN_BROADCAST;

	/* reset fi to prevent gateway resolution */
	fi = NULL;
} else if (ipv4_is_multicast(fl4->daddr)) {
	type = RTN_MULTICAST;
} else if (ipv4_is_zeronet(fl4->daddr)) {
	return ERR_PTR(-EINVAL);
}
