downstream OFDM SNR????
I just connected a new netgear CM1000V2 because my old zoom modem had to be rebooted about once a day to to lock-up (would lose connection completely). Netgear seems to have solved the loss of connectivity. I pay for 300mbps plan and comcast speed test shows my downstream is 200mbps +/-. House desktops and TVs all hardwired with home run connections to aggregating PCs<->Gig-E switch <-> router<->cblmodem. After a lot of reading-up on modem signal levels, I am questioning my downstream OFDM SNR - its 30-31 db. All other downstream channels are 35-39 SNR. Power levels look good (downstream running 0-4dbmv). Uncorrectables are very small.
