There are potential DOCSIS 3.1 issues with any version of MoCA (1.0, 1.1, 2.0, 2.5).
This is because DOCSIS 3.1 establishes new downstream and upstream frequency ranges. The overall frequency range will be extended in two stages: first to 1218 MHz and then to 1794 MHz. These improvements enable DOCSIS 3.1 to achieve transmission rates of up to 10 Gbit/s in the downstream and 1 Gbit/s in the upstream. Anything basically above 1 GHz can conflict with MoCA.
The only solutions we can provide are:
1. Ask ISP to provision the line for DOCSIS 3.0 mode (if user wishes to keep using MoCA)
2. Discontinue using the MoCA devices (if user wishes to retain the DOCSIS 3.1 mode and speeds)
3. Identify an alternative home networking technology such as G.hn or wifi to replace the MoCA
