Hub 5B re-boots every 4 to 5 days

[m0sbf]

I am trying to get to the bottom of why my Home Hub 5B re-starts every few days. I am trying to get my line speed unbanded and the constant periodic re-boots from the router aren't helping as the DLM counters keep getting reset.

I'd appreciate it if someone could take a look at this event log and offer any advice/help. The router restarted at around 13:08 today, with no user intervention.

I have a Home Hub 6 on the way, so may try that to see if it is more stable.

Another disconnection. The hub never made it to 4 days without another re-start. Please, someone any ideas what is causing all these disconnections:

you didn't say what you have tried in an attempt to solve the disconnections

can you post router stats please

are you currently using test socket with a filter?  if so have you checked that there is no dial tone at all your extension sockets whether in use or not?

try quiet line test  dial 17070 option 2  should be quiet and best with corded phone

[m0sbf]

Thanks @imjolly

I have a dedicated 2nd phone line, which has no extensions connected to it. It's not a socket that you can take the front off, for that reason. There is a microfilter connected and I have changed this a few time, with no discernable improvement in reliability. I did a quiet line test and the line was silent. Of course, that doesn't mean that some noise burst on the line doesn't happen once every few days. I will repeat a quiet line test for a longer period and report back. 

I have a brand new TP Link VR900 v2 here which I might connect this afternoon, if I get time. Although the line hasn't been up for 24 hours, so I don't know whether another WAN disconnection (with me commissioning the new router) within the same 24 hour period is wise? The TP Link is supposed to be pretty reliable, so it remains to be seen whether it improves things.

Here are the stats from the HH5, which show a banded 44MB/10MB profile that I am trying to remove, but the WAN connection drops every few days so the DLM counters will never allow rate increases, as it stands. Hence I may try the TP Link for a while:

so unlike most beople you have a separate line for your fibre connection so no problems with wiring

if you switch to the tplink then go into hub and disconnect internet from there rather than just unplugging or switching off power

[m0sbf]

Thanks @imjolly

Yes, I have a dedicated line with separate wiring for broadband. I have a dedicated BT line box in my office. In the old days of ADSL this gave me 8.5MB connection, whereas the other line to this house (with extension wiring from the faceplate) barely gave me 3MB. 

I'll see if I can find time to fit the TP Link today. If not, it will be done imminently. Thanks for the tip about internet disconnection from the hub. Does the DLM see that as a requested disconnection, rather than a failure of service?

[imjolly]

basically it is just the hub and a controlled shut down as against a sudden loss of connection

[m0sbf]

Thanks

[m0sbf]

@imjolly If you're interested, the TP Link VR900 v2 is now installed. Very easy to set up (5 minutes). Seems to be working well on BT VDSL2. WiFi performance is better than the HH5B. 5GHz is particularly good; in some extremities of the house it's stronger than 2.4GHz, which is odd.

A laptop the other side of the house gave 40MB download speed on 5GHz, so it looks pretty decent.

HH5B Max data rate before swap: 16522 / 54519

TP Link VR900 v2 after swap: 16481 / 57923 

Actual Rate (banded as the same) - so there is no actual data speed increase: 10000 / 44000

S/N Ratio HH5B: 11.7dB / 9.3dB

S/N Ratio VR900 v2: 11dB / 9.8dB

I can't see any VDSL uptime status on the VR900 and line stats are very basic. I'll have to ask their tech team as I want to keep an eye on WAN stability. I don't want my line banded any lower due to disconnections.

The unit runs just slightly warm and power consumption doesn't look that dissimilar to the HH5B.

[imjolly]

Sounds good so far hope that continues
