Windows 10: No wireless networking on my tablet

I upgraded from Win 8.1 Pro on a Microsoft Surface Pro Tablet. I mistakenly went ahead with the install of Win 10 Pro without correcting a Wifi error. Now I do not have any wireless networking on my tablet. One option is to go back to Win 8.1 Pro. Is there a way to insert a updated driver or something to get my wireless working?
