Lost MDD Timeout and RCS Partial Service

Over the last week or so I have been suffering extreme drops in speed where the connection drops down to a handful of KB/second and struggles to load even simple HTML.

During these periods I found that in the router log the errors being displayed are Lost MDD Timeout and RCS Partial Service. (See below).

This doesn't seem to be happening at a particular time of day, just at random intervals.

Is this something I can sort or will an engineer need to come sort it out?

Many thanks Smiley Happy

Re: Lost MDD Timeout and RCS Partial Service

Hi DeadToast,

 

Welcome to the community and thanks for posting.

 

Sorry to read that you are having issues with your broadband connection.

 

I've managed to locate your account and the upstream power levels are too high at +53 dBmV. For this I would like to arrange for an engineer appointment to check this for you. I've sent you a PM (purple envelope icon, right corner) with some details for you to confirm please.

 

Hope to hear from you soon

Sam

Re: Lost MDD Timeout and RCS Partial Service

Okay, so the problem stopped for a few days between our PMs and the engineer coming. My power levels are now within standards (after a visit on the 10th of Feb).

However this morning I have noticed the speed dropping and found that the same errors are popping up in my network log.

What can be the problem?

Re: Lost MDD Timeout and RCS Partial Service

Hi DeadToast,

Hope all is well. Thanks for getting back to us and apologies you are still having broadband time-outs.

Since the router has been online there has been 11 time-outs reported within 6 days. As these are not real-time they could of happened on day one then nothing since. There were no faults on the day you posted nor any issues with SNR (signal to noise ratio) on the network.

If you can reboot the router and hopefully this will reset the network log, if they continue post the log again please. Also it may be worth creating a Broadband Quality Monitor to check the performance of the connection. If you do create a BQM you will have to disable the firewall within the router settings.

Do you notice these disconnections when you are online?

Speak soon

Sam
