WiFi deteriorates after closing the lid on Surface Book connected to Surface Dock

This problem has all the symptoms of being a hardware issue, so I wouldn't get my hopes up too high that a driver/firmware update will fix it.

Just want to add that this is still an issue with the latest firmware.... my solution has been to keep a microfiber cloth folded over between the lid and keyboard when its closed and docked...

I also observed the same issue here... My experiments showed the following:

• If it is not connected to the surface dock (and not connected to the power cable as well), the internet speed does not change when I open or close the lid.
• Location matters (I moved the book at differnt locations on the desk, and the symptom differed)
• The impact to the uploading speed seemed to be more serious than that to the downloading speed.
• It was interesting to see that flipping the direction of the connector substantially affected the internet speed. Specifically, when the connector's cable (I don't know how to call this...) goes toward the front of the book, the deterioration was not as bad; but when the connector's cable goes toward the rare of the book, the uploading speed dropped close to 0.

Hope these experimental results help, and wish Microsoft gets this issue addressed asap! - it greatly affected the user experience, as no one wants to run without internet!!!

It's probably the strong magnet they used to keep the lid closed.  I would guess the the plastic strip at the top is where the antennas are housed, and that magnet is throwing things off.  I'm a bit bummed about it as I just went and purchased a monitor to dock this thing to.  I've suffered from a few of the SB bugs, but this one is a bit disheartening.

Also having this issue.  165 when open, 15 when closed.
