This the generic driver that comes with the Generic Wireless 300n Mini Wireless USB that is usually on Ebay or Amazon. If you are using Windows 10 you can pretty much plug the device in without having to install the drivers as Windows 10 does recognize the adapter and has drivers for it. In any case if you really have to install the drivers that are on the mini cd-rom that comes with the adapter they are below, because no one has a cdrom on their laptop these days. This adapter sells for $4 to $5, and I must say the results are pretty amazing, I was able to get much faster speeds and range on laptop after installing it. It also has a RP-SMA connector so you can connect a high gain antenna or Yaggi for longer range and even faster speeds. After owning a few of these, I can report that they don't last long and are extremely unreliable.
