Re: Think Broadband Ping Monitor Results (POST YOURS)
I have seen quite a large number of 12Mbit users on 1 upstream on the VM forum

The new firmware was tested over the past 8 weeks with 2000 customers including volunteers from this forum and we've seen no significant issues in testing.
The new firmware enables 100Mbps throughput for our forthcoming 100Mbps service and is also designed to improve upstream stability and throughput. It also turns back on the TDOX feature that was switched off in July with the 10.12 firmware, due to a bug affecting performance.
BTW, note VM saying that the VMNG300 was fit for 100 meg.

LMAO, wish someone would have quoted that when Mark posted about the 92Mbit limit

You can ACK a whole RWIN with a single ACK (instead of, say, ~50 or so which is more usual). As you mention though, it doesn't work effectively in all scenarios (i.e. I did say zero packet loss)

Thats what I thought until my neighbour was put on 12mbit without bonding and I seen reports on tbb with the same.

Re: Think Broadband Ping Monitor Results (POST YOURS)

Re: Think Broadband Ping Monitor Results (POST YOURS)
What sorcery is that? That graph is perfect!
Mine is fairly okay during weekdays but it goes off the rails over the weekend, especially Sundays. Not as good as yours by far though!
