Thanks, and if the ISP sets the band and/or target SRNM, do the stay set?
Reason for asking is that for the last year we've been reliant on using the router config to over-ride BT DLM to maintain the proper speed. A&A had said that they can't fix SNR target on 20CN as we were then, but they'd have more control on 21CN. We've just been moved onto 21CN, still in the 10 day training period. A&A now a little vague about what can be done, I can see error messages back from BT in response to their attempt to set band and SNR, but that maybe because it's within that 10 day period.
Meanwhile performance on 21CN is absolute crap.
20CN was typically just over 4 meg, for example
"Down Sync=4224kb/s LoopLoss=55dB SNR=5dB"
On 21CN it just seems worse in all parameters for example ..
ADSL2+ "Down Sync=3068kb/s LoopLoss=57dB SNR=4.4dB"
ADSL 2 "Down Sync=3068kb/s LoopLoss=53dB SNR=3.9dB"
Just getting a bit concerned that we've been sold a pup and far from improving things, 21CN is a big step backwards. Should I go a step further and disable ADSL 2 as well, effectively reverting to 20CN type modulation?
