They may have a driver at the manufacture site. If you are going from win 7 to win 10 you might try the win8 drivers if they have them for the nic.
This is the risk you take, there are still lists of devices that are not compatible with win10 and that is just from the people who were testers. I suspect we will see much more of the more uncommon devices.
I am assuming the belkin is your router, it doesn't matter the brand of the router only the manufacture of your nic card.
