Hi, welcome to the community.

Have you noticed an issue when line attenutaion upstream is 0bm?

Best regards.

Hi, Thanks for the update.

Normally, Line attenuation indicates how much the signal has degraded between the DSLAM and the modem. This is largely a function of the distance from the exchange. The lower the dB, the better for DSL signal strength.

If the internet connection is unstable, it could be better if you could provide the whole details of the DSL status, such as SNR margin.

Best regards.

Thanks for the update.

Please install the beta firmware on the following link to see whether it helped with the network stability:
