Connection was perfect before christmas 80mbit down constantly but one of our children unplugged the router instead of the christmas tree lights Sad which caused dlm to resync at 69mbit. Over the next week the line rose steadily to 80mbit again as you can see from the stats but throughput is stuck at 60mbit going through a cat 6e cable directly to the router.

 

I have this problem constantly with dlm as it seems to get stuck, i spoke to tech support who done a gea test and my upstream and downstream are very good. Min speed was 53mbit max 79 average 76 which isnt right at all.

 

This is what is showing on my account on the plusnet side

and yet my sync is 79999 to the router.

Here is my billion router which uses the same chipset as my huwei cabinet

Re: Maximum FTTC 80/20 sync but only 60mbit max throughput

Hi there, 

 

It looks like our systems hadn't caught up to a change in DLM just yet but I've updated the profile manually from 70.2mbps to 78mbps so you should see some improvement now.

Hi thanks for the reply, I’ve ran a speed test and getting the same speeds as before.

Can you run another gea test and post the results back please.
