I'm getting ping spikes and sometimes consistantly high ping mostly in overwatch and fortnite. We have a 100/100 fiber connection at home and since I cant route a cable through the house we instead got a high performance router and I'm now gaiming over wifi. I have limited the up and download speed to minimize bufferbloat and I have tested this in dslreports. The webbsite shows that my bufferbloat is very low.

When I play League of Legends, just as the numbers suggest, I'm getting a low and consistant ping of 30 to 40. However when I play other games such as Overwatch and Fortnite(especiallt when I'm landing) my ping will ocationally spite to between 150 and 300 and sometimes stay there until I ragequit the game :(

This all just doesnt make sense to me since it works just as it should in some games but terribly in others. Do anyone know what this might be? Does anyone has fix?

Multiple gamers won't give you bufferbloat. Each person is using 100Kbs. It's a single download or someone streaming video that causes bufferbloat. streaming videos usually cause bufferbloat to happen on and off, because they don't download constantly.

If it is bufferbloat from bottlenecks in your...

does your router show total band usage?
bufferbloat only happens when it's swamped.
limiting speeds won't correct it. AQM will, like FQ_Codel.

I'd test with ethernet. either buy a long cable and run it all the way on the floor or move your pc.
if it's fine on ethernet then it's the wifi. powerline or mesh wifi might make it better. I'd consider getting a quote for putting in ethernet if it's a long term place for your pc, as that is the only good solution to fixing it.

You need to do some more careful testing to see if the problem is your related to your internet connection or it is a wifi issue.

I would agree it will be fairly inexpensive to buy a long ethernet cable and run it over the floor just to test. It will quickly let you know if the problem is related to your internet connection or it is wifi. Wifi is known to cause exactly the problem you describe with games and there really is no fix other than to not use wifi. Still it could be a problem with your pc or the internet so you have to test to be sure you are fixed the correct problem.

Powerline can suck worse bufferbloat-wise than wifi: google for: Interactions between TCP and Ethernet flow control over Netgear XAVB2001 HomePlug AV links

But you still miss the KEY factor in bufferbloat. You have to be exceeding the units capacity for data to queue. Most people using powerlines have only a single machine that is running their game connected. This pretty much ensure that there will be no overload....and if they are stupid enough to run torrent in the back ground while they play there game I just laugh at them.

Wifi can have massive issue due to outside interference even running a small fraction of the capacity. In most cases there is no way to resolve this interference. At least on powerline you are in control of all the devices in your house.

Bufferbloat is just a symptom of a too much usage of a connection. The only real solution is buy more bandwidth

Thanks for the answers. I later founf out im getting high ping in all games from time to time and that my bufferbloat levers are sometimes gets really bad when we are multiple people gaming at ones. It can't really be the wifi beacuse never had this issue on my old pc and my brother (who is sitting closer the the router than me) never had this issue so I don't really know what to do at this point, guess I just have to live with it...

If it is bufferbloat from bottlenecks in your ISP package then QoS is very effective.
$50 edgerouter X will keep your latency low as long as your connection quality is strong with a 75-97% limiter on it.
downloads max your bandwidth, more bandwidth only makes the bufferbloat not last as long. fq_codel works extremely well if your line isn't under-provisioned. you can download as much as you want and have multiple people play online with low ping.
