This is an I-O DATA wireless LAN adapter, model WN-AC433UK. I purchased it 7-8 years ago and intended to use it for a small communication device, but I ended up connecting via wired connection, so I only tested it to confirm it worked and then stored it. Please see the HP for detailed specifications. https://www.iodata.jp/product/network/adp/wn-ac433u/index.htm It has been stored for some time. The packaging has no significant damage. Thank you for your understanding, and I appreciate your consideration.
