Hi guys!

Me and my sister have 2 computers we use in separate rooms. I'm using the router wired, and she's accessing internet via Wi-Fi. We also both have smartphones, I have a PS3, etc.

Is it possible to somehow set up internet so I don't have lag in games when she tries to watch youtube in 1080p or something. She doesn't play any games and isn't tech savvy at all, so it won't matter much to her because all she uses the internet for is surfing.

Someone told me this router could do this, are they right?

This statement from the description would seem to support that:
"IP based bandwidth control allows administrators to determine how much bandwidth is allotted to each PC"

How much overall bandwidth do you have coming in to the house?

I have not seen this routers limits before so its hard to say how they really implement them. Technically it is not actually possible to do what you want since you can only process packets that your router has in its memory but by the time the data is in the memory it has already used up the bandwidth to get to the router. So if a internet application sends 10m to you using all your bandwidth your router can drop say half of it and only present 5m to the end PC. It would now appear to the end PC that you are only using 50% of your bandwidth but in reality you are using 100% but just trying to trick the PC.

The only reason this partially works is that the PC will see the data loss and tell the transmitter it has errors. These errors causes retransmissions which causes the transmitter to slow down for short periods of time. If the application does not respond in this way and slow down this form of bandwidth limiting will not work. It does work for youtube though.

What you need to do is limit the maximum rate for your sisters PC to some fraction of the bandwidth. Since I have not used this router I do not know if it wants the internal IP's or maybe it wants youtubes ip. It will takes some experimenting.

Yes that router has Qos (quality of service) but check you current router hasn't already got it, what is it? it may be named differently.

quality of service works very well i use it myself for the same reasons.
