Repeated disconnections

Hello,

 

I have been a Plusnet customer for coming up to 3 years now. Generally, service has been good. However, in the last week I have experienced frequent disconnects - many times a day.

I am on 40/10 FTTC using a Plusnet Hub One. Here is an excerpt from a log around the time of a disconnect:

Does that offer any clues as to why these disconnects may be happening? Is there anything else I should be looking at?

Any assistance to make my line stable, as it once was, would be greatly appreciated.

 

Thanks.

Re: Repeated disconnections

Openreach have probably swapped your line with another customer who complained and given you their bad line. It's the standard way they fix line faults.

Login to your router.

Boot

 

Do you have anything like this?  "Boot reason: watchdog reset (cause: 0x3)"

I've had >100 of this particular failure since August 2020.

0x3 does seem to be a known problem with the Home Hub One and the similar BT HH5.  I've actually just logged on to search for it.
