I needed an affordable yet powerful Wi-Fi adapter for my desktop and after a lot of searching, I found the TP-LINK TL-WN722N available on Amazon.
According to their website it features:
Exceptional wireless speed up to 150Mbps brings best experience for video streaming or internet calls
Easy wireless security encryption at a push of the WPS button
4dBi detachable antenna, remarkably strengthen signal power of the USB adapter
The package came within 3 days and this is what it looks like:
The adapter was plugged into a USB 2.0 port on my Windows 8.1 laptop and it was automatically installed and ready to use in under a minute. It is slightly stronger than my internal Wi-Fi adapter, at the same moment my internal card recognized 31 networks while the TP-LINK recognized 34. I tested it for several hours streaming 1080p videos on youtube, opening 12 tabs at once on chrome and multitasking, and streaming music on iTunes radio and it held up very well. The connection did not drop once and so far it has been great.
