Yes, the audio glitches even when there is minimal or no traffic, as long as it's connected to an AP. As long as there are spikes, there are problems with the audio.

I did try it and like I said, the spikes are there but nowhere near as bad as when I am connected. Also, the same spikes are there even when I turn wifi off completely, so I don't think they are related to the wifi. I don't see the point of trying to solve what's causing those spikes though, when the wifi is making it 100 times worse.

The audio glitches happen pretty much anytime there is a spike.

Yes, I am connected to AP and download/upload is happening. When I am not connected, but the wifi is turned on, the spikes are minimal, similar to when I turn off wifi.
