Hi,
Our line is slightly noisy, and also suffers from reduced SNR during the evening and overnight, typically dropping from the target NM of 6dB down to a highly variable 4.5-5.5dB. The line doesn't drop, but my ISP reports that we're getting errors. How many errors I don't know, my router doesn't report them, and the ISP's view appears to just be the number of errors within the current 15 min period when they look (so could be from the last 900 seconds, or only a few, depending on when in that slot they grab the data).
Anyway, thinking about this, if there's noise on the line when the modem trains up, it should avoid the noisy frequencies - is that correct?
If so, then maybe rather than making sure I always reconnect during daylight to get the best speed, should I reconnect in the evening to give it a chance to work around the dodgy frequencies. I can force target NM and basically get it to connect at whatever speed I want, but realistically it's not going to run fast enough to get a 4.0meg IP profile, so connecting at just over 4000K synch speed could be the best compromise.
Does this make sense?
Thanks, Tony S
