While true, QoS traditionally has a negative impact on straight data transfer to favor media transfer.

Maybe there's a virus on the network that's broadcasting?

 

QoS is like adding in a bunch of traffic lights all over town. It doesn't change the speed limit.

 

I still don't know why everyone's assuming there's some sort of problem.

It was working fine before, I clicked QoS on and I get more bandwidth over wireless.

There's 3 computers connected to this router, maybe someone's running something in the background.

Seems to me having some prioritizing of traffic is not necessarily a bad thing when there's more than one user involved.
