Constant random dropouts everyday.

Hi, for about 2 weeks now My broadband connection has been dropping out randomly. The hub light goes to yellow/orange, then after a minute or 2 goes back to blue. Sometimes it will happen repeatedly every few minutes or at other times every couple of hours. Longest connection I have had in this time is 21 hours. After several calls to BT, resetting the router, factory reset, replacement router and an engineer visit where they replaced the old faceplate and tidied up the connection outside the building saying their was some slight corrosion to it. (which was this morning). The conection then seemed to hold until just over 3 hours later when it started dropping every couple of minutes again.

Just cycles this over and over each disconnect. The snr margins have gradually dropped on each dropout though, started at around 17 each. I have lost about 10% speed as well over the last few days possibly because of the large number of disconnects.

Re: Constant random dropouts everyday.

Hi @Maki12

 

The speed issues you are seeing are normal because DLM will report a line instability issue, and will band your connection to provide a more reliable service.

 

I'd recommend ringing BT back up and get them to look at your line stats, they should be monitoring the line if you have reported a fault, i'm not too sure if you can identify between session disconnect and a line disconnect.

Openreach say a Session Disconnect is the ISP's responsibility as its software related, rather than physical. 

But if they say its a Line drop, then thats a problem with openreach's equipment somewhere, theoretically your line should always be active, and when you get disconnected its still active, but just got timed out for some reason.

 

I had the same issue, ring BT up and get a Fibre Optic engineer out, (if they will let you) they like sending out installation engineers that sometimes cant touch some of the equipment. 

 

If you had corrosion on the line, did he mend that, or did he just neaten the wires up? ideally he should have freshlt cut the cable and jelly crimped the pairs back together.

Re: Constant random dropouts everyday.

I'm not really sure, as the connection box is up under the edge of the roof. Think he said he neatened it though. He was out there for about 10-15 minutes.

 

They didn't send an engineer out at all until the 4th call, every time they did a remote line test and said it was normal except the last one where they noticed some kind of line fault. Wondered if that meant the fault is intermittent and is going to be hard to pin down.

 

Any ideas why I am getting so many DHCP requests? I wasn't getting any at all until after the engineer had been today. The tunnel up and tunnel down messages also didn't start until I replaced the HH5. On my older HH5 the only message I received before a disconnect was the PPP send termination request ones.
