Re: Infinity 2 activated, speeds vastly slower than estimates, only 1432kbps up!

OK, so quick update.  Things have been relatively stable with the Type A HH5, the DLM even disabled interleaving on the line and I was getting 49/14 D/U which I was happy enough with (even though I lost 4Mbps off of my upload for reasons I don't fully understand).

 

However, I today swapped to my Billion router and an unlocked HG612 so I can get some real stats for the line and use a router over which I have full control.  Weirdly I synched at 42/18, losing 7Mbps down (eek) but gaining 4Mbps up (yay?).  I seem to get a huge variation of sync speeds depending on which device I connect with and I don't know what's going on, does anyone else?  For the sake of reference, here are some nice stats and charts out the HG612 in case anyone can spot anything obvious:

I guess at this stage I'm trying to work out why my downstream varies by up to 10Mbps depending on which device I use, and my upload by 5Mbps or so, is this normal variation?

Re: Infinity 2 activated, speeds vastly slower than estimates, only 1432kbps up!

Realised I wasn't on the latest HG612 firmware so I updated, resynched and... lost nearly another 2Mbps off my upload. 😞  I just don't understand why things are so inconsistent and all over the place.
