Dropouts

[Jamesvolvo]

hello all

so - I've been having some problems today and wonder if I could get some advice.

FTTC, VDSL. Normally get 65-70Mbit/s down, 20Mbit/s up. Usual ping time when wired direct to modem is about 10-12ms.

TP-Link VR2800. Wifi is lots of Eeros but Wifi is irrelevant to today's fun.

All afternoon I've been getting long dropouts (several minutes). While this is happening nothing works at all at the IP level, no pings, nothing. While this is happening the modem seems happy and I don't think the VDSL is dropping. It always looks like this, whether or not the ping is broken. I'm pinging 8.8.8.8 and 1.1.1.1, and both behave the same.

So far so bad, but now I'm confused. The BT guy in the chatroom said that they can't look at this until I have a BT hub, and they're going to post one. He kept saying that the non BT hub would cause interference issues, and that they can't run proper remote diag on it. He's saying that the line is checking out fine and there are no IP issues in or near my exchange.

He had me factory reset the TP-link modem which made no difference, and I restarted it a couple of times. I've put it back up to the latest revision.

Any thoughts? How do those line stats look? Whenever the ping is working, I get 65Mbit/s on fast.com. Doesn't feel like a VDSL problem to me but I thought it would be good to check here.

As of now things have improved a fair bit without anyone changing anything else, but I don't want this coming back.

Ideas welcome please

The non BT hub causing interference is a complete load of tosh.

Its not a VDSL problem if the modem reports those figures when your problem occurs.

It could be your router giving problems or it could be a BT problem. Impossible to tell.

Thanks. I hope they keep the chat logs. 

Anyway I’ll plug the BT hub in when it arrives tomorrow and then perhaps I can get someone to investigate properly.

Hi @Jamesvolvo and thanks for posting.

It's possible the TP-Link has devloped a fault but let me know how things go with the new hub.

Cheers

Slightly unsure what happened here - the problem seems to have resolved itself without replacing the TP link modem - but I put the BT smart hub in anyway and it, too, seems to be working fine.

The BB was bad for about 48 hours altogether. I guess if it goes bad again then perhaps having a BT hub will remove an excuse to avoid investigating...
