And another one: Repeated HomeHub 5 restarts

I see I'm not the only one here to be suffering from repeated and regular restarts with a HH5. Mine started a couple of weeks ago, after several weeks of mostly problem-free operation. 

 

I've already been in touch with CS and and engineer visited last Wednesday (15th). My line is fine, but he swapped the HH5 for a new one, just to be on the safe side. He also reset my line speeds after they'd dropped from the constant restarts. This fixed the problem for a couple of days, but now it's back with a vengeance — something to do with a router update in the meantine, perhaps..?

 

  • BT Home Hub 5 (Type A)
  • Software version 4.7.5.1.83.8.173.1.6
  • Last updated 16/10/14

I've now started counting. I had eight restarts in the space of five hours on Tuesday evening (I stopped counting after 10:50pm) and four or five last night, also around 10.50pm. There was also at least one more during the night — the restarts break part of my home network when they happen, so there's always a tell-tale trace. My download speed is so far largely unaffected by this week's problems, but my upload speed has now dropped from ~18Mbit/s to ~3Mbit/s. 

 

This is now back in the hands of BT CS, bit I thought I'd add a new thread here to add my voice to the many others experiencing this problem.

Re: And another one: Repeated HomeHub 5 restarts

Looks like you have a line fault and DLM has taken action to reduce your speeds to raise your noise margin due to many disconnections.

A BT engineer checked the line last week and said it was fault-free, but I guess I'll have to see what the second round of investigation reveals.

You said he reset your DLM. As the fault wasn't fixed DLM will just take the same action again with the same result.

Re: And another one: Repeated HomeHub 5 restarts

I don't understand... If the engineer comfirmed (presumably to the best of his ability) that the line was free from faults, how can a line fault be causing the problem..? My reading of this is that the repeated router resets are the problem — could that be triggered by a line fault, or is the DLM kicking in because the router appears to be struggling to maintain a stable connection?

Re: And another one: Repeated HomeHub 5 restarts

DLM is reacting to errors and disconnections it has measured on your line, as you can see it has mainly affected the upstream.

As you have already had a replacement Homehub, the chances of 2 with exactly the same fault are slim in my opinion.
