A Place to Store My Cache 
In case you are having issues with your wireless failing to connect on your Surface Pro 2, I'm sharing what worked for me. I was having some issues with the wireless adapter crashing when resuming from sleep. It would usually take 2-5 resumes before it would crash, but I wasn't able to fix it without restarting. Nothing would show up in the wireless adapter settings.
The full error message:
Windows Network Diagnostic
Issues Found
The Marvell AVASTAR Wireless Composite Device adapter is experiencing
driver or hardware related problems.
The wired network adapter is experiencing problems.

I was able to fix it by installing the latest firmware and driver pack from the Microsoft Download Center, for some reason I wasn't getting these updates automatically.

Extract August2013SurfacePro.zip. Right-click Marvell\WLAN\win81\x64\mwlu97w8x64.inf and select Install. I also went ahead and installed the rest of the included drivers. Reboot and the problem should be solved! I expect these updates to get pushed out automatically in the future.
