If I swap to the old HH3A (using the 10/100 ports), without restarting the Openreach HG612, the upload is back to normal and as soon as I change to the HH3B again it is reduced. The speeds are also normal if I setup a direct pppoe connection to the Openreach HG612.
It all seems rather odd to me, as what is the likelihood of receiving two faulty HH3Bs. Or, maybe I've just been very unlucky. It's starting to feel like a firmware issue with the HH3B (V100R001C01B031SP12), but then I would have expected a lot more people to be reporting the same issue.
I'm currently using the old HH3A, as I rather use the 10/100 ports and have faster upload compared to low upload and working gigabit.
Has anyone else experienced this with the Home Hub 3B, or have I just managed to get two faulty units?
