Summary: My acer laptop's built-in wireless adapter is not very good. It keeps dropping connections and "freezes" all the time. The TP-Link USB adapter works great....no drops and no freezing! I like it so well I am going to order another one for my wife's computer.
Summary: great price if it worked. I am not computer savy but three different people who are tried to make this work. They are all good with computers and could not get it to locate the router. As a poor old granny I do not recommend this product.
Summary: I purchased a refurbished computer on line that did not have wifi connection, after reviewing several wireless adapter on the Wal-Mart website I decided to purchase the TP-LINK N150 Wireless Nano USB Adapter (TL-WN725N - my first attempt to install did not work, not sure if it was the USB port was the problem, one I install in another port and install the adapter and CD at the same time - all went well, follow the instruction for set up its working very very well.
Summary: I am sure it would work for Windows 7 or a Mac (haven't tried it in a Mac) soft ware just does not like Windows 8.1 Pro. Price was good but I should have gotten the Linksys AC/N adapter that works I have Windows 7 computer that I am going to try it in. You get what you pay for, buy cheap get cheap.
