Figuring out cause of my dropping line sync
« on: February 04, 2017, 08:02:44 PM »

Hi,

I've had my line for about 10 days- performance has been alright although I've had a few drops which in the early days I put down to DLM, recently its been adjusting downwards more :(

My line's attainable is reported as 57Mbps and I've had syncs in the order of 50-55Mbps for most of the time. But, in the last few days, its dropped to 43Mbps. I just setup a Raspberry Pi to pull the stats from the Zyxel VMG1312 modem and plot at MDWS (same account name there).

When I had the line installed I'd asked it to be a new line but OR decided to just activate the existing line. The line runs through the wall to a porch/hallway and then out into a box which is fixed under the roof and then connected to the line that comes from the pole. I'd guess this line is probably about 5-10m long. I've attached pics to see whats going on (OR sent an engineer out to connect the old socket- he put a new cover on for the outside box- wires were hanging out before).

I'd love to know whether people think the current wiring could be a big factor, or whether there's data in the MDWS to suggest is noise/interference etc.

Thanks!

Your Hlog & QLN looks good I take it your old master socket was updated to NTE5a with a SSFP MK2 or MK3 and you have been using a Vigor 130 in the past there does seem to be a DLM cap on your line at the moment.

As you have just started to upload to MDWS did you notice any random disconnections on your modem/router in the past.

I think we will need to see a few days worth of statistics via MDWS but, having reviewed your earlier posts, there is a possibility that either the circuit is banded or the DLM process needs sufficient time to recover from your previous usage of the Draytek Vigor 130.
