I've been having issues with my FTTC line. For about two years it was syncing at 20 Mbps down and was stable. Recently it went to DLM-imposed 10 Mbps. I spoke to the ISP (Zen) who reset the DLM.
The line is now syncing at around 20Mbps but is not very stable.
You lot are very knowledgeable, so I thought I'd ask here in case anyone is able spot any issues with the below or suggest troubleshooting strategies. Thanks!!!
P.S. I am about a kilometre away from the cabinet (wire length).
