Dynamic Line Management reducing connection speed (below 5Mbps)

Go to solution

Hello, after 3 months of major broadband connection issues (moved into the property in July) I have enjoyed one month of comparatively stable service (it seemed that a firmware upgrade for the Superhub drastically improved the stability of the connection).That is not to say the connection hasn't dropped over the last month: it drops daily but with a few exceptions, is back up again in a few minutes. Compared to before, when the connection was down more than it was up, I can live with this.

 

Unfortunately, it looks like Dynamic Line Management has stepped in to reduce my speed from about 15Mbps to under 5Mbps. I think I need a moderator to help me arrange for an Openreach engineer to reset the DLM before the speed drops any lower. Can anyone help please?

You can call the technical help desk and request an engineer visit.

Are you connected to the master socket or an extension?

Thanks for the response, Webby. For the avoidance of any doubt, I have been through the BT process again and again and again. Believe me, after the trouble I've had, we are way beyond "the technical help desk" and "connected to... an extension".

The reason I posted here is because, alas, the only way to make any progress is with the assistance of the moderators who monitor these forums from time to time.

There is little point in resetting DLM if you still have an underlying fault. That needs to be fixed first.

Hi licquorice, after 7 engineer visits, no underlying fault has been detected. My line passes every test with flying colours. I agree resetting the DLM once a month isn't ideal, but in the absence of any other solution, it seems to be the only way.

The fact that the firmware upgrade had such a big impact suggests that the problem is software related, if not a fundamental problem at the cabinet itself.

Connections don't reset without reason. Regardless of how many engineer visits you have had there is still an underlying fault somewhere that needs to be resolved.

I hear you and, trust me, I feel it having been on the sharp end of it for months! But if an engineer came out now, he would once again inform me that there is nothing wrong with the line and so there is nothing he can do. He would also mention the fact that I'm over 2 miles from the cabinet and therefore its a miracle that I even have a connection!

The fact that the firmware upgrade had such a major impact certainly supports that and needs to be reflected on. The only thing an engineer can do is reset my DLM.

Which theoretically he is not allowed to do unless he clears a fault.

Have you considered buying either a third party router or an Openreach modem?

Sure, I think they call it a "broadband boost" which means do the checks, see that everything is okay then reset DLM.

Yes, I bought a Netgear Nighthawk. My current setup is that the Smarthub is connected directly to the port. WiFi is off. I have one single Ethernet connection to an Ethernet switch and that then relays the connection around the house (through two powerlines, one of which is then connected to the Nighthawk modem which does most of the heavy lifting, including on WiFi).

Once my DLM has been reset, I'm tempted to swap the Nighthawk with the Smarthub... For now, I'm trying to keep the Smarthub on continuously to encourage DLM to increase speed.

DLM won't care if it is the Hub or the Netgear connected to line and if its the hub that's causing the disconnects you will be better off connecting the Netgear.
