Upstream forced to qpsk????
Hi all,

i'm running docsis2.0 on my plant.
Downstream : BW 8MHz, modulation 256qam -->result = 35mBit/s (ok, i'm satisfied)
Upstream : BW 6.4Mhz, modulation 64qam --> result = 2.4MBit/s
BW 3.2Mhz, modulation 64qam --> result = 2.4MBit/s
BW 3.2MHz, modulation 16qam --> result = 2.4MBit/s
BW 3.2MHz, modulation qpsk --> result = 2.4MBit/s

So it looks like my upstream modulation is forced to qpsk???

my Upstream SNR = 30.3dB and CNR 26dB, so that should be suficient...

anyone any ideas?

Thanks W.

Bear in mind that this is an independendant forum for Cable subcribers in the UK. You are welcome to participate, but if you have a specific problem with your cable modem, you'd be better off contacting your cable supplier.

As you are from Belgium, I have moved your thread outside of the VM section to avoid confusion.
