Ping in games usually sits around the 30-50 mark depending on what game im playing (usually either dota, smite and now some pubg). Problem is when somebody else wants to watch netflix on a smart tv ping generally fluctuates anywhere between about 120 and 220 so is not only alot higher but wont sit at any kind of stable number.

The simple QOS functions on my netgear nighthawk router have not helped to fix this in any way, so my question is with the QOS functions on this router, hyper traffic and anti flood functions, will this help reduce the effect on games that somebody watching netflix will have. Im not expecting it to magically make it so that there is no effect at all but is this going to help the situation.

If you connect it right, and set it up correctly then it will magically make it so that there is no effect. While uploading/downloading my ping only increases about 10ms which you wouldn't even notice while playing a game.

I'm not an expert in BT, but lots of other users here are and could help you getting it setup properly. As you said, put the modem into modem mode which disables any routing capabilities so your Netduma can handle all the devices and stop any chance of lag while gaming. With those speeds using the Netgear for an AP is kinda overkill as the Netduma wifi will do just fine. But if you need 5ghz then sure you can use the Netgear

Last question really, when setup correctly this should reduce the impact on gaming which is great, not to worried about no impact reduced down to a manageable level is great. Will this affect the people trying to watch netflix by limiting the bandwidth and reducing quality or causing buffering, or will the features on the router re-order the traffic so that more gaming oriented packets aren't queued behind netflix and other downloads? Just trying to get an idea of how this works.

As MoD says. When it's working correctly you shouldn't even know when Netflix is being watched or not. They wouldn't notice a difference either, they shouldn't get any buffering. If you use hyper traffic specifically as well then your game will always be the number 1 priority on your network.

Please would you connect your gaming device directly to the Hub with an Ethernet cable and ensure you have no powerline adapters or ethernet switches are connected.
Are you using the BT Hub? If not please connect it up and check the ping.

Unfortunately there would be no way for me to setup the Xbox directly at the BT hub due to the layout of the house and the hub being connected to a phone line. On the game the ping would sit at an average of 60-70ms (no lag) however spike in intervals to 150-300ms constantly if someone is streaming Netflix etc.

I'm having similar issues. Speedtest shows high download/upload speed and low ping, however while gaming or streaming I am experiencing huge lag spikes between 3-10s long. Pingplotter shows around 30-60% packet loss on third hop (which i'm guessing is BT's headend). I've spend around a week troubleshooting this issue and i'm at my wit's end

Hi David, I'm connected through wireless WiFi my Xbox directly to the hub, no adapters or se secondary routers are in my house. The hub is also in a room beside the room with the Xbox so it's not a range thing.

I'm on an 80/20 FTTC package with a nice short line length, so achieve a good sync speed with very low error rates - zero Error Seconds downstream and 674 upstream in last 20 days - full details at and

However, as soon as anyone in the house starts using streaming services - particularly Netflix, things go wrong. The Netflix client appears to pull down content in distinct chunks - bursting to use around 10-12Mbps every 4 seconds or so. Each time that happens, I see my latency increase hugely which makes VoIP calls painful. Example below (and yes, this is all Ethernet, no WiFi to blame here):

It also seems I'm not alone in this. It's been brought up on the Plusnet forums quite a few times and never seems to be resolved - instead people focusing on it being a copper line/VDSL issue. To me it seems to quite firmly be a backhaul or network QoS issue.

Example here: -Broadband/Intermittent-High-Ping-Particularly-if-Netflix-is-Stre... ... which seems to be precisely what I'm experiencing. The thread also links to this huge thread on BT forums confirms this is a thing on the BT network: -setup-Wi-Fi-network/Recent-online-gaming-ping-spikes-when-streaming...

Can someone from Plusnet advise what causes this please, and how to work around it? I find it hugely annoying that I have to put up with this, whilst a friend using a Sky Broadband FTTC connection with similar/worse line properties to mine, hammers it constantly and gets this:

I've gone through your previous forum posts and my first instinct was to ask if you experienced these problems before you migrated onto the closer cabinet but I see that the issue started on the 1st July this year.

There are two things I'd like to try, adding a static IP onto your account and arranging an engineer to investigate further as it's not uncommon for errors on a port at the cabinet to cause packet loss issues where we're not seeing anything wrong.

We'll start with the easy one first, so I've added the static IP on temporarily I hope because either way this shouldn't be a permanent solution. I've also had to drop your PPP connection momentarily to apply it.

Unless I'm mistaken, big yellow spikes aren't necessarily bad as that just indicates the connection is being used. What's bad is the red packet loss at the top. Unfortunately we're unable to view the link you've posted as this appears to be blocked internally. Are you able to embed a live Quality Monitor stream into a forum post or send us a direct link to it?

We also don't have any traffic prioritisation or management policies on our network, I believe we removed that in 2017 and as you've tried a static IP then the issue would highly unlikely be related to our network.

Having said that, have you tried to do anything time sensitive like VoIP or play online games since the static IP was added? If you're still experiencing problems, I think we're best off progressing this as a fault with our suppliers because there can be numerous causes for packet loss issues and latency spikes while streaming.

Before we go down that path and arrange an engineer though, would you be up for trying a Hub One? Happy to send you one as part of this troubleshooting. This should rule out any issues with the models of routers you've been using.

I would agree that a bit of yellow isn't in itself a problem.... The problem is that it's so pronounced when streaming to even a single device in the house. If, instead, I kick off a regular download using all of my bandwidth, the latency doesn't rise by anything like as much. So it's either that traffic to/from iPlayer, Amazon, YouTube, Netflix, et al is treated differently, or the bursty nature of these transfers causes some sort of anomoly.

BTW... whilst I have your attention, could you take a look at my billing please? Earlier in the year I was mis-billed (missed a couple of months, then a big single bill, then a few months of over double what I should be paying)... my monthly payments are now correct but I believe I've over-paid by around 40 and I can't work out a sensible way to get this refunded/corrected. Could you nudge the appropriate folks please? Thx

Hi @Bobsta thanks for the extra detail. Actually before I order a new router I'd like to discuss this further with a colleague. I'm not sure what impact this would have however we use something called caching for popular streaming services such as YouTube and Netflix. I'd hope I'd be able to come back to you tomorrow but I may need a couple of days.

@Gandalf , when you have that conversation, could you also find out whether the use of Plusnet caching CDN is determined by the use of Plusnet or third-part DNS ?, i.e. presumably using Plusnet DNS would point to your caching CDN servers, whereas I'd assume that using say Goggle DNS pointing at the streaming service provider's regional servers (such as Netflix) would bypass Plusnet CDN - or is that stream somehow intercepted by your network ?, as this may be another variable with @Bobsta 's problem (if it is caching related).

@Bobsta Not been able to catch the right person yet to talk about this so I've posted a question on their portal now and I'll let you know when I know more although I'm out of the office tomorrow, but I'll follow up on Wednesday. I've also and hopefully sorted the issues with the billing of your account.
