It's been a week since having Infinity2 installed and I was informed I was synched at 80/20.
However, speed tests at BTW and speedtest.net indicated that while download is within expected range (73-75Mbps), upload, when using HH3, only ever reaches 9Mbps at best.
I expected a bit of "settling in" and so left it for a few days, until day 5, when I came accross a couple of threads in this forum stating that others had similar issues until they replaced their HH3.
Although I would rather have an all-in-one sollution modem and router, I cannot afford the outlay currently, and so I went for a TP-Link WR841N to replace the HH3.
Speed tests on BTW and speedtest.net with the WR841N immediately showed improvement in upload at 15-16Mbps, and small improvement in download at 74-76Mbps.
So, it seems there is *some* issue with the provided hardware in the HH3 - hardware or firmware? - I suspect firmware, although I am no expert 🙂
I wonder if the HH3 was at fault for my non-Infinity2 ADSL issues..
I did have the HH3 with standard ADSL and I performed a full factory reset when Infinity2 was installed.
