Re: Power levels wrong

What are your upstream power levels?  Downstream levels are low as should be between +10/-6

I work for VMO2 but all opinions are my own and are based on my own experiences

Re: Power levels wrong

Yeah upstream is also low (opposite to downstream) should be between 33-51.  It will need an tech visit to adjust your levels.  If you have an attenuator fitted anywhere, try removing it.

Re: Power levels wrong

You can try phoning customer services or wait a few days for a VM staff member to get to your post.

Re: Power levels wrong

This isn't being fixed without an engineer visit, almost certainly it's a bad joint or damaged cable somewhere between yourself and the street cabinet. The downstream power is too low for the hub to properly get the information it needs to configure the upstream channels which is why you only have one rather than four and that one is 'shouting' at full volume in an attempt to get through.
