Re: Downgrade to ADSL

After just over 3 days up time Hub reset itself this morning, mercifully it reconnected at previous rate for download, 36 meg upload was less than before. No obvious reason from the log.

Re: Downgrade to ADSL

Here I go again, the usual quarterly reduction in speed, last one in September. On 16th December a TRO69 command re booted my HUB 5. The result an immediate downgrade in speed from around 40mb to 30-32 on download, sometimes a lot lower. Ping increased from 18 ms to 27. Since then my HUB has rebooted itself another 3 times, the most recent occurrence on 29th December. I firmly believe there is a fault in the CAB caused by a hardware/software update. On the last 3 occassions I have had this the most effective solution was the engineer resetting my port in the CAB, result instant and visible speed increase back to 40 Mbs.

Clearly nothing has been learnt from the previous experiences so I guess I have to go all through the loop again of fault reporting just to get the port reset in the CAB. My house wiring has been checked thoroughly and the last engineer said how well it had been done.

Re: Downgrade to ADSL

can you post stats from your hub again please   there is no physical reset of a cab port which gave you a speed increase if was a DLM reset which can be activated remotely on engineer request

Re: Downgrade to ADSL

you had a reset just over a day ago and speed now at 35mb with attainable 40mb which is similar to previous stats you posted

did you try quiet line test  just because nothing has changed does not mean you cannot now have line noise or interference  dia 17070 option 2  should be silent apart from announcement and should be done with corded phone

Re: Downgrade to ADSL

Thanks for that. Just did a speed test which shows 32 on download , my IP profile is set at 33.88 which as I understand it means I will never get more than that, certainly not 38-40 which I was getting. Doesnt explain why the ping has suddenly gone from 18-27 ms, ie response time is longer. Why does a DLM reset cure the situation ? Why does my line not return to it's original state instead of being in a reduced state ? Something happened to my line and/or the CAB on 15/16th December which caused the current issue.

 Will try a quiet line test as you suggest.

Are you able to request a DLM reset on my line please ?

Re: Downgrade to ADSL

DLM system is used to control the performance and stability of related lines, which in practice means that your speed may go up or down depending upon how stable / error prone DLM thinks the line is. Broadly speaking the DLM system on Openreach’s FTTC network works pretty well, although sometimes a connection’s profile may become stuck at a lower level or other problems can occur that might benefit from a profile reset.

please see the above article taken from ISP Review this year confirming a profile can get stuck at a lower level.
