Up for your review is a open box tp-link tl-wn851nd 300mbs 2.4 GHz Wireless Adapter . I found it will not run in a windows 10 environment. Go figure TP Link going end of life on a 300 mps wifi adapter. LOL. First 10.00 get this. Original owner and still in the box both mounting brackets and driver disc. Right now the low profile is mounted. This is useful if you need a PCI adapter for windows 7. I never could get it to work in Windows 10..
