As a workaround you could get a cheap USB Wifi dongle. Other than that, try getting the drivers from the chipset manufacturer's page (you'll have to find out what chipset your Wifi card uses, be it Atheros, Broadcom, Intel or something else), they might be newer and work better with Windows 10. Also try letting Windows find the drivers itself through Windows Update if you haven't done that.
Generally there are 3 ways to get Wifi drivers, either from the wifi card manufacturer's website, from the wifi chipset manufacturer's website or from Windows Update itself, they will all likely be different drivers as the chipset manufacturer will have more generic drivers that are designed to work with every wifi card using that chipset, the wifi card manufacturer's driver will be made to work only with that specific wifi card or with a range of their wifi cards, and Windows will just try to find the one that matches your card (but won't neccessarily find the latest version, which would more likely be on the wifi card manufacturer's or the chipset manufacturer's website and could work better)
