Hello TPG, I am broadband adsl user since last 2 years at this same residence. My ADSL Line quality was very good since begning and DSL used to sync at 18mbps downwards. However line last 3-4 days it has reduced alot.  Speed test result: http://tpg.speedtestcustom.com/result/1aada420-7d16-11e8-90ce-d96e74141b29 See the result of my modem below. I have tried changing modem as well as Splitter , but result remains the same.  I have visually inspected patching at my appartment mfd, it looks clean and tight.  Can you please check at your end and advise what could be the issue? or port reset at your dslam??     Downstream Upstream TCM(Trellis Coded Modulation) On On SNR Margin 8.2 dB 5.4 dB Line Attenuation 24.3 dB 24.5 dB Path Mode Interleaved Interleaved Interleave Depth 32 2 Data Rate 6570 kbps 410 kbps MAX Rate 8016 kbps 444 kbps POWER 0.0 dbm 12.3 dbm INP 1.9 symbols 1.9 symbols CRC 85 20   ...
