Editor's Pick: If your desktop doesn't have a built-in WiFi card and running an Ethernet cable is a hassle, this little gadget plugs right into a USB port and gets you online instantly. It supports both 2.4G and 5G dual-band connections, so streaming videos and gaming stay smooth and stable. It's super compact—once plugged into the back of your tower, it barely takes up any space. It also works great as a quick fix for an older laptop with a faulty wireless module that you'd rather not repair.
