Repeated drop outs on ppp layer

on ‎04-02-2022 2:42 PM - last edited on ‎06-02-2022 4:51 PM by

Hi,

For the past month I have been having drop outs on the connection.

Most last only a few minutes, but they happen once or twice a day now.

 

Is it possible to see if this shows up on the PlusNet end.  I still don't know if the problem is mine or the ISPs. Sad

 

Router log of latest drop:

The VDSL modem seems completely happy though:

Thanks for your post @venquessa

I'm really sorry to see you're having drops in your connection.

I've tested your line tonight, and the tests aren't showing any issues, but I can certainly see the drops. I've attached a graph below showing this. As your modem's holding sync, it's potentially unlikely to be a wiring problem.

Do you happen to have another router you can try to rule out your existing one? 

[edit]

Here's also a copy of the testing I've just ran:
