For sure something happened to your line. Noise, bad contacts, wet lines, bad modem DSL-input driver or whatever.
SNR is what it is, the difference between signal and noise.
SNR margin would be how much you have spare and you could use it for higher sync (or let it be for better SNR with less lost bits)
Now you have 6dB SNR and thats needed for reliable transmission, your line wont get faster as it is running on its limit right now.
If you get back 15dB you could go faster by reducing SNR and DLM would step up again.
