I am on the Virgin media XL 30mb option not having any problems just wondering if i am getting the correct signal levels. Using a Superhub if that matters

why do all superhub configs say atdma for upstream when non-superhubs say QAM16?

Doesn't matter, just had a read on the cisco website, sounds sweet

I am waiting for mine to say 40960kbit on the upstream as I am seeing jitter rise during the day with no upshifted speeds yet so still not enough capacity for it.
