Wireless adapters are compatible with a range of routers, including N300, N600, and AC 1200 routers, and are capable of delivering a range of speeds, from 150 Mbps to 1200 Mbps. All of our TP-Link wireless adapters are ultra-portable USB adapters that you can carry anywhere for wireless connectivity on the go. Wireless adapters come in two varieties – ones that fit inside your computer, and ones that plug into a USB port on your computer. If you’re using an older laptop or PC, a USB wireless adapter provides an easy and instant way to upgrade your wireless connection so you can make the most of the faster speeds on offer from the latest WiFi routers. USB wireless adapters plug straight in and get you connected instantly, allowing you to connect to your WiFI router without cables. PCs and laptops need wireless adapters to receive wireless signals and get online.
