Latency and Drop out issues

[TheDiamond]

For a number of days now I found myself being kicked from game servers and had frequent crashes while gaming online. I also had similar issues trying to work from home.

I decided to investigate as the vodaphone tools always said that everything was fine. I started by downloading a chrome extension called "Internet Connection Monitor" (Would recommend) and ran it.

I was terrified by what was reported back to me. I was getting dropouts on a regular basis. Often multiple times in a single minute. It also reported that there where major issues with latency. It would hover at maybe 20 ms for a while then shoot up to >1000 and then back down. I have also tried running speed tests on my connection. It shoots up to 80 or so Mbs then suddenly it throttles down to about 30/40 Mbs.

I checked the router logs to be confronted by a ton of errors, none of which I understand.

Can anyone shine a light on what may be happening? I have restarted the router e.t.c and that has had no noticable effect. It is utterly of no real use at the moment and trying to get through to support stresses me out so much I feel like screaming.

Sorry about the late reply but it fixed itself and I thought that was problem solved but sadly it has all of a sudden gotten worse. The device is just a straight forward Wireless usb adaptor which works fine and always has done.

My current problems are incredible. Look at these stats for the last couple of days :

Via my phone I managed to contact vodafone who gave me a 6 digit fault reference number.

When I chased this up the automated service asked me to enter the ref which they said they didn't recognise. No suprise there! All the automated service did was tell me to go online and start the whole process again. I am going around in circles.

On top of that my upload speed has gone down to 10 Mbps while my upload is around 80.

Christ I am so stressed. This should be vodaphones problem and not mine.

Just as a heads up, the original issue could be caused by a misconfigured switch, or once upon in my case, after me leaving an ethernet cable hanging out of a switch where someone tidying up after me then plugged the other end of the cable into the same switch.  It will generate some of the errors you are seeing and will eventually crash most routers.

You still haven't confirmed what service you are on, but assuming you mean your download is 80, I assume it is FTTC, and if you are getting a sync of 80 you are fairly close to your cabinet.

Not sure where you got those stats from but I would think you have a line fault which Openreach will need to investigate. (Vodafone will need to call them out)

Have you tried with the router in the test socket to rule out problems at your end?

[TheDiamond]

Not shure what you mean.

Are there any instructions anywhere so I can try this out?

My plan is New Full Fibre 2

Then the test socket comment doesn't apply to you, it's only for FTTC.

It's also unlikely to be a line fault then.

[TheDiamond]

Oh Jesus, this means I am going to have to deal with support or lack of.

My blood pressure is going through the roof. I have had 70 disconnects today alone and my download speed is 14 Mb/s. May as well communicate with the server with 2 tin cans and a piece of string.

How are people expected to work with this?

Thanks for your efforts. You should get a job woth vodafone and show them how to operate.

Now that we know you are on full fibre (FTTP) we really need to start again, many of the previous replies assumed you were on FTTC.

For a start we need to establish if you really are getting disconnects, the browser extension you are using may not be reliable. It possibly can't identify the difference between Wi-Fi drops and line drops.

As I'm on FTTC I can't be sure just what the router (I assume you have the THG3000) gives you in way of statistics.

Is there a possibility you could try using an Ethernet connection, and see it the problems still occur, I'm wondering if it is just Wi-Fi that is the problem.

[TheDiamond]

Tried Ethernet and the same applies.

I have noticed that every single time I get a drop out I see the following line often many times over in my Router Log file :

Failed to send DHCPV6 message to ff02::1:2 (Permission denied)

Between 5:00 pm today and 5:42 pm I got no less then 51 drops in connection and my log showed :

This always corresponds with the drops.

I wish I knew more about networking.

[Ripshod]

The DHCPV6 messages are irrelevant. Vodafone don't provide IPv6, everyone has those messages. If you've suffered 51 disconnects you need to look for a poor connection or damaged cable somewhere.
