Hi, The speed test indicated the download speed is at around 35Mbps, while my plan should reach 50Mbps. I checked the cable modem status page. There are 8 channels running QAM256, symbol rate for each channel is a little above 5M symbols/sec, SNR is at 44-47db, the power level is close to zero dbmv.
Does this sound good, or the symbol rate / SNR is too low to reach 50Mbps? If I calculated it correctly, it should be 8bits/symbol(QAM256) * 5M symbol/sec * 8(channel) = 320Mbps theoretically?
Please help have a check,
