Selected ADSL routers on VECTOR firmware support adjusting ADSL SNR value by typing the command "adsl snr" in router's command-line interface With this command, we may reduce SNR value to improve the ADSL sync speed, or to increase SNR value to improve the ADSL stability. Below shows how to use this command.
1. Enter the router's command line interface.
2. Enter command
adsl status to check the current SNR value. The below example shows the current SNR Margin is 8 dB.
3. Enter command
adsl snr ? to check how to use it.
adsl snr 50for the router to try synchronizing with an SNR value 5dB higher
4. After ADSL restarts, enter command
adsl status to check the new SNR value. We can see the current SNR Margin increased to 11 dB.
NOTE: The new SNR value will not be exactly the value of 8 dB plus 5 dB. It is because the actual synchronization result depends on the negotiation with ADSL IPDSLAM; however, Vigor Router will try to get synchronization with a higher SNR value.
If the SNR value or the ADSL stability is not as good as you expected, please try other ADSL modem codes to improve
