Lag spikes when somebody else is using the wi-fi

Whenever somebody else uses the internet from another device(browsing, watching youtube, streaming music), the internet is slow for everybody else and games are unplayable.

For example, if I am playing TF2 and then a family member starts watching a youtube video, the game will become unplayable for me, ping goes crazy on net graph.
However, if I am playing TF2 and I run a youtube video in the background, it is unnoticeable. So to be clear, the problem is not the internet bandwidth (15MB down 1MB up), its about "using" the router. (I don't really know how to describe)

If I'm playing TF2, browsing gets slower for everybody else. (even though it is only KB/s).
If I watch youtube/stream, browsing gets SUPER slow for everybody else, and pages might even not load.
Obviously, the same is true vice-verca.

The router is an Edimax BR-6524N.
I ping <1ms to it.

When there aren't more than two people using the internet at the same time, everything is stable.

Is this how things are supposed to be on Wi-Fi? Would getting a new router solve the problem?

You'll need to adjust your router QoS settings to prioritize your computer.

Type 192.168.0.1 into your web browser. It's in your router settings.

It's usually 192.168.1.1 but it's sometimes different. Type ipconfig in cmd and look under "Default Gateway" to see which gateway the router uses.

Well it's a bit different for every router/firmware so I can't be too specific but you just need to find a way to prioritize your computer via IPv4 or MAC address.

I did it, nothing has changed.

Try prioritizing TCP/UDP ports 27000-27050.

Are you using 802.11n while the other devices are using 802.11g?
AFAIK, G and N on a 2.4ghz frequency can fuck each other over.

I would try falling back to wireless-g only. (General setup>Wireless>Basic Settings>Band)

edit: look at fix #3 http://www.smallnetbuilder.com/wireless/wireless-basics/30664-5-ways-to-fix-slow-80211n-speed

OMG yes they are using G and I'm using N.
I'm in the middle of a game but if this is the fix you are a legend!
Fingers crossed!

Sharing wireless wifi is a lot like sharing underwear... It's pretty disgusting. Better off running a cable if possible.

Sorry for bumping a 3-year old thread. But I have exactly the same problem.

When I'm the only person using the internet, I don't experience any lag issues. Whenever someone starts watching a youtubevideo or something similar, I'll get lagspikes. I think it started when I bought a new pc. However, I also got lag recently on my old laptop, which I never experienced before. So I don't really know what exactly the problem is.

Could the problem be, explained in [#10], be the cause?

I had this problem as well. Wound up solving it by buying some powerline adapters. Would have been a huge upgrade; went from 30-80 ping on average to 10-30, even with many people on the wifi. Only problem is I bought the cheapest ones available, like $15 for a set from TP-Link, and they like to disconnect at random. Sometimes it's once a week, sometimes 3 times a day, and I have to un and re-plug the adapter to get them to reconnect. Luckily the whole process only takes about 2 seconds for me, but if your power outlet is out of arm's reach then definitely do not go for the cheap option. also if you do not like the .0001% chance of you losing connection for a second during a fight

anyway point of the story is powerline adapter work good

I could give it a try. I just think it's very weird since it happend from one day to the other. Certainly there must be something causing this.
