Downgrade from BT Infinity 2 to BT Infinity 1 - will DLM be reset?

Hi,

 

I have been on BT Infinity 2 for some time but the max download I can achieve is 25Mb so its not worth staying on the upto 80Mb version so have requested to be downgraded back to BT Infinity 1.

 

With the change in product will be line be subject to a DLM reset (as currently I think I'm on a banded profile) and another 10 day training period to determine a stable connection?

Thats a shame I was quite hoping I would be! Am worried that I won't be getting the full speed if it stays banded.

Can you request a free of charge DLM reset or removal of banded profile?

WHich HH do you have? If a HH5 you can get the stats from the troubleshooting/helpdesk in the browser interface. Post lines 1-13.

 

If a separate medem and hub run as speedtest HERE and click on "Further Diagnostics" post back the full result.

 

Also post the result from HERE using the checker.

I was using a HH5 and it was constanly disconnecting. So have since swapped to my own Netgear router and an unlocked HG612 Openreach modem so I can monitor the stats.

Re: Downgrade from BT Infinity 2 to BT Infinity 1 - will DLM be reset?

I was swapped over to BT Infinity 1 this morning and the downstream interleaving has been reduced from 800 to 19.  BT speedtest now looks like this:

Lets hope the line can stay like this 😉
