snr margin
You must modify the connection and consider the path you follow to lower the signal-to-noise ratio.
It seems like you're referring to an ADSL connection and mention having a TP-Link modem/router. Let me know how I can assist!
I attempted to adjust it using the command line, but I realized just how to modify the downstream SNR margin. Now I'm searching for methods to adjust the upstream SNR margin.
I won't use random commands. Instead, I'll focus on making physical adjustments like wiring or other changes.
When the upstream SNRm is very high, two things could happen: The connection quality is poor, and reducing it will likely cause more frequent drops. The ISP may have limited your upload speed; lowering it won’t help because that’s a fixed maximum they set for your modem/router, not the SNRm itself. In my experience with ADSL, I could lower the downstream to 3dB and get stable performance, but trying to adjust the upstream was extremely unreliable. This is probably because upstream usually draws less power and is more affected by interference. Additionally, changing settings depends heavily on the modem/router, making it hard for anyone to assist effectively without knowing the exact issue.
