Downstream sync speed

My downstream sync speed has dropped to 19.2mbps on fttc broadband. It has been at roughly this speed for about six days. My minimum guaranteed speed should be 29.2mbps. I had to unplug the router a couple of times last week, not sure if it’s a DLM issue. Any help would be appreciated.

Re: Downstream sync speed

Hi @kidneybean1965 I'm sorry that you're seeing some slow speeds at the moment, that must be really annoying!

 

It looks like DLM has dropped it down, however the connection seems to be stable again, I've popped a DLM reset through for you and it should improve things over the next 24 hours for you.

Re: Downstream sync speed

I wonder how many people have a drop in sync speed and do not notice for a while?

My sync is 22Mbs and every now and again drops to 11. 

A router rebbot usually fixes it but surely modern technology should be capable od correcting itself?

Re: Downstream sync speed

Okay, thanks for your help. I will keep an eye on the speed and let you know when it returns to normal.

Re: Downstream sync speed

@TeeGee there is a technology known as SRA (seamless rate adaptation) although I've only seen it used on a G.fast connection.

Re: Downstream sync speed

I have waited a couple of days for the speed to improve, but unfortunately it has remained at 19.2mbps.

Re: Downstream sync speed

Sorry that's no better, would you be able to try a test whilst the router is connected to the test socket? https://community.plus.net/t5/Library/Testing-From-The-Master-Socket/ba-p/1322242

I am getting a download sync speed of 40mbps with the router connected to the test socket.

Re: Downstream sync speed

Thanks for letting us know, that could mean there's an issue with the socket, do you usually connect the router to it via a separate filter?

Re: Downstream sync speed

No the socket is an Openreach MK4. The engineer who fitted it said it does not require a separate filter. I have the router plugged into the test socket using a filter at the moment.

Re: Downstream sync speed

No worries and thanks for confirming, just to check do you have any other devices connected to other phone sockets if you have any?

Re: Downstream sync speed

Fix

@kidneybean1965  It's possible that the modem resynced at the higher speed after moving the connection to the test socket. You will probably find that it will be the same if you put the faceplate back and connect using the built in filter. Give it a try.

If the speed drops there must be a problem with your master socket/faceplate.
