Hello,

I have a strange situation.
When i tweak the SNR via Telnet on my W8960N with :

adsl configure --snr 80 or more ; i havent problem, the SNR drop to 8/9 (for example)

but with

adsl configure --snr 79 or less ; my SNR drop to 5/6/7/8 (for example - depend to value) but a few second later, i see the SNR back to 9->10->11 and then -5/6/7/8 (same value that initial SNR with the snr tweak but negative ) and finaly desynch

whats happened ? for information, i have the latest firmware

thanks
