Not bad but your upstream is really good even though your downstream is -4 to -5 mostly. are you using the SBG6580? Earlier today my SNR was at 42 dB (usually that's what it is normally) but now it's between 37-39 dB. Why is that?

yes it is a SBG6580. There are swings in the SNR when the temperature changes especially when it goes from cold temps to hot temps which causes the cable to expand and contract.

I think it's Time Warner doing something because it always does that from time to time. In the past it did that. I doubt its the temp or weather cuz even in bad weather my signal is dead on perfect so. I think it boils down to the ISP (Time Warner Cable).

So what issues are you having with your perfectly acceptable SNR levels.
