General discussion related to Cable Modems, DSL, Wireless, Fiber, Mobile Networks, Wireless ISPs, Satellite, or any other type of high-speed Internet connection, general issues and questions here. Review and discuss ISPs as well (AT&T / SBC, BellSouth, Bright House, CableOne, Charter, Comcast, Covad, Cox, Cablevision / Optimum Online, TMobile, Verizon FIOS, Shaw, Telus, Starlink, etc.)
You should be able to sync at 6.5 Mbps unless the noise fluctuates a lot.. I would try to bump up the tier and see how it works out. With ADSL2+ and downstream attenuation of 35 dB, the approximate distance is 2.53km and the maximum achievable speed is like 11Mbps. Of course then you have to factor in some type of noise safety margin, but still, 2 Mbps seems too conservative.

Hi Philip, I'm actually on a 1Mbps account with a 2Mbps line, internet in South Africa is still quite expensive.
What ticks me off is that the last mile (not literally) of copper is such a high AWG, way too thin in my opinion.
Also how do the output power figures look?
If they could up the output power would that help?
Low upstream power (dBmV) is actually good. The higher it is, the louder your modem has to transmit to be heard. Higher downstream power otoh means clearer signal. I wouldn't worry about your power figures. The only thing that can be improved on your end is getting fewer downstream "HEC errors" - those are caused by poor RJ11 cabling, and/or no DSL filters on the line. Even if you can't get them to zero, one should try keeping them at a low number.
Other than that your signal looks ok to me, and as you said your ISP is capping your connection.
