I previously owned a XP Media Center PC and a XP Pro laptop.

I had them networked on a wireless N network, which also included my Xbox 360.

I never had any issue transferring files between the PC and Laptop or streaming videos/music to my 360.

Fast forward. I now have a new PC and a new laptop, both of which run Windows 7 64bit.

I have the home groups set up. I also have them set to share with the 360. All the folders show up and I can share files between the three... HOWEVER...

Streaming video to the 360 hardly works, as the video will constantly stop to buffer. And whenever I try to transfer a file over the network between the PC and laptop, I barely reach 1MBs.

After searching around the net, I found some people suggesting I uncheck Remote Differential Compression. I did so on the PC and laptop, restarted both, and still had slow transfer rates.

Any ideas?
