QAM64 wont support 100meg stable connection.looks like my 100mb connection linked with qam 64 which means i think my connection sever shared with 30 and 50 meg connection users in my area.
its complete rubbish
my connection upgraded from 50meg to 100meg
but i am only geting 35meg to 45meg all the time.its a complete cheat by virgin#
they should supply 100meg after the local infrastructure upgrade into 256QAM
i am getting this connection without any attenuator attached
A better question would be who thought it was smart to release 100Mbit in an area running on 64QAM.
There's less than 150Mbit/s available total for every device in this area sharing those 4 downstreams, in other words whenever the area is running at over 33% utilisation OP won't be able to get 100Mb.
Hopefully when this gets picked up on questions will be asked and the necessary work to get 256QAM running done sooner rather than later. This will increase the available bandwidth to a shade under 200Mbit and, if capacity is the problem, give OP his missing 50Mbit overnight.
