I have customers who have run Win 10 with no issues. I have a Surface Pro 3 with Win 10 and have been fine connecting up to my lab Meraki AP. Have you tried calling up Meraki support? They have been very helpful in the past when I have reached out to them.
I have in the past with my surface, had to uninstall the Marvel NIC card and reboot my machine and then install the new driver make sure you download the new driver when you uninstall the Marvel NIC and drivers. That has fixed issues with my Surface. I have the latest driver and that seems to work the best. The issue was when the Surface goes to sleep, it would come back and not connect to any wireless SSID's.
