Those are over the course of 20 seconds or so.

Refreshing the status page shows the SNR of all but the first downstream channel fluctuating between 30dB and dropping completely. The first channel stays rock solid. No fluctuations in usability, speed, ect. Anything to worry about or look into? Can't say I've ever noticed it doing this. I don't like seeing things change when I haven't changed something.

Also just noticed, had multiple upstream channels yesterday. Just one today. Weird.]]> http://www.dslreports.com/forum/Downstream-Channels-Dropping-Fluctuating-SNR-27238292 Thu, 14 Jun 2012 17:06:40 EDT
