Running Ubuntu Gnome 16.10 on a Thinkpad t450s and Android Nougat on a Oneplus 3t.
I’m getting really inconsistent transfer rates. They began at a few MiB/S but have since dropped to about 20KiB/S and now to zero.
Another strange inconsistency: my main phone (Oneplus 3t) is syncing to two devices, my computer (t450s) and an old android phone (HTC One M8) I use as a makeshift syncthing server to back up photos. On the Oneplus 3t, both the T450s and the One M8 always show the same sync level (“Syncing xx%”).
Reading around the forum, I get the impression that connecting via relay and IPv6 could be relevant here, but I’m having trouble understanding how to troubleshoot this. Any help appreciated!
