I mistakenly uninstalled my dLANdll.dll card - any ideas how I can get it back?

[sue99]

It was on my PC - my recycling bin is empty - I did a system restore which brought back my internet connection back but it still says I am missing the my dLANdll.dll card. It shows up whenever I when I attempt to download the software for my newly purchased D-LINK wireless USB. I updated my software from Windows 8 to 8.1.....any thoughts of how I can recover it?
