Streaming problems. Slow download speed (MBPS) on Sony Google TV?

I have a Sony 46" Google TV hooked up to high speed broadband via wifi. Streaming from any video source has become a huge problem. When running internet speed tests on it, I'm getting download speeds of 2.7MBPS. My laptop computer sitting right next to the TV, also connected via wifi, downloads at over 10 MBPS according to the same speed tests. Does anyone know why the Google TV downloads so much slower? Do you know of any settings adjustments or other solutions to fix the problem? Thanks for any help.
