This Morning Status
I thought this might net a better response than calling in, as that didn't do much last night (did nothing in the end).
I have the 30/3 Mb internet only package in the Columbus, OH area, except that I'm getting anywhere from ~1Mb/~3.3 to the full 30/3. I had a random loss the other day (Saturday, Jan. 12, 2013) early in the morning (8ish if I remember), and since then have had no reliable speeds, with many page dropouts.
Using speedtest.net, hopping around Ohio based test sites (Cinci gives the lowest ping of around 13-15 ms).
Looking at my DS channels, I have two that are showing a few uncorrectables. (I'll try to post some pictures, or data here)
This is what I woke up with this morning after doing a test. Sorry for the poor formatting. Basically DS channels 2 and 5 aren't doing so well, and 5 is below the 33dB SNR that I have noticed seems to be the spec. US has zero issues, and has been running very well since day one.

The uncorrectables tend to increase after a speed test. I'm also getting MDD Timeout notices and such in the logs. The tech I spoke to last night blamed my modem (An Arris CM820A) which is about 7 months old, and has performed flawlessly until the past few days. The only thing to happen outside in the past few days has been the snow melting, which makes me wonder if something physical is not quite sealed. I had 3 bad channels prior to the reset, and now two, but the overall errors I get now are much higher (maybe 200k errors total before, in several days, vs a few million overnight).
The errors listed were all reset last night during the call to WOW support. Ultimately it was suggested I lease a modem (which won't help with a noisy line if I remember).
I attached the screenshots of the status and log screens of my modem from last night and this morning. I also ran PingPlotter last night, keeping a thousand entries about pinging Google for a couple hours last night. Ping was slightly varied, but I was getting 30-40% packet loss according to the program, which I think is a bit high. I had tried the standard CMD ping -t, and that was showing a bit better swing of between 3 and 40% packet loss, averaging out to be about 10% (this was before the reset).
Also, when doing a speedtest, it will slow way, way down, to say 4 Mb, and then shoot up almost instantly to 20ish, then down to 11 and such. Highly inconsistent.
To finally sum this up, does anyone have any suggestions about this. I'm not much of a modem guy, but this does not look like the earmarks of a failing or defective modem, but of a noisy line. Any help here is appreciated.
