Cable Forum - View Single Post - 50M Is my Downstream power level and SNR right?

After a few months of complaining, VM decided to repull my cable and replace a brand new one to fix my upstream power level which was at 58dBmV.

Before the repull, my downstream was fine, somewhere between 5-6dBmV and 41 to 42 SNR.

After the repull, glad to say that my upstream power level is at 39dBmV, but now my downstream levels seem messed up!

Is this even right?
