Default [Q] WiFi question

I'm not sure how to ask this.
Is the WiFi throttled somehow on this phone?

Or can your isp tell that you're using a mobile device or, vice versa, your cell carrier knows when you're on WiFi and throttle to make you use data instead?

I'm getting .2mb download speed on WiFi and 22mb on speed test.
YouTube buffers almost every 10 seconds.

ZERO problems on 3g/hsdpa

let me know if more info is needed....
