Connection issues: Lag Spikes in games, variable pings and issues with Wifi Calling. 9% packet loss

Go to solution

Hi to all,

Looking for some information and help.

I'm having the issues above for the last 2 weeks - 2-3 second delays in games that the family play, variable responses on other devices and issues with Wifi Calling.

The gaming is primarily World of Warcraft and was absolutely fine previously - the connections are all wired and the whole network we've reset a few times, including trying with just one PC connected over the weeks to make sure there's nothing else interfering, I've also tried using different ports to the router. The same PC at a friends house performs fine.

We've tried the online troubleshooter with BT but everything reports fine and it moves to trying to sell us a wifi extender for our wired issues (clearly not necessary)

 

BT Wholesale test:

BT Home Hub Stats:

I've run a quiet line test and all seems ok.

Using the speedtest app shows the following including quite some packet loss:

I haven't called the helpline yet as last time I had some issues (back with ADSL) they blamed the homehub and tried to charge me for a new one despite not using a home hub.

Any ideas to try?

Before I call the helpline - what other information do I need to arm myself with to provide them with?

 

Adam.

Forgot to mention - our connection drops for 5 mins or so at least 2-3 times a week with the hub cycling orange, red broadband light then eventually reconnecting. This happens at random times and can also repeat several times in a short period

have you tried using the test socket with a filter to see if that improves your stability

you say all connected by ethernet is that direct to hub or using powerline adapters?

Thanks for the reply.

I've not tried the test socket no - I'll do that and report back later. The issues weren't prevalent 2 weeks ago on the same connection and that's not changed.

Normal config is hub -> switch -> PC but I've tried with a direct connection to the hub also and no difference (tried multiple hub ports).

Once you've tried the above and if that doesn't fix the issue could you ping google or something

(ping -4 google.co.uk -t)

to see if there are any spikes when pinging.

Could you also post a trace route to any website so I can see what hops you're going through and potential correlation with my issue. Here (https://community.bt.com/t5/Home-setup-Wi-Fi-network/Latency-Variation-Ping-Spikes-during-online-gam...)

tracert -4 google.co.uk

You could alternatively use PingPlotter to see the possible jitter and the amount that's happening at each node.

There was no difference going into the test port.

For ping - 4 google.co.uk -t:

Approximate round trip times in milli-seconds:

tracert -4 google.co.uk:

Can you get PingPlotter and post a screenshot of a 10min ping to the same IP?

Not seeing anything really except the 1000ms on the google hop.

Same issue, insane late spikes when I launch any game for the last 2 weeks. I've honestly had enough they either need to come out and say there are issues with the network or I'm switching to another ISP because I can't keep going like this where I can't play when a simple 480p video is playing simultationally.

It's as i expected really.

This is either an exchange issue or the issue is within hop 3 or 4 (31.55.186.XXX).

That 3rd hop sometimes responds to ICMP requests or it doesn't, in your case it didn't respond at all. We can't see the first hop because it's configured not to respond to ICMP Ping requests which is fair enough.

I also get high ping and or packet loss on those two nodes (3 & 4) but in your case it doesn't seem like you get very high ping but you do get a huge amount of packet loss.

I would be curious, if you wouldn't mind, put on a twitch stream www.twitch.tv pick any stream and re-do the ping plotter. I'm curious to see what your ping variance is when you're watching a  live stream.
