Ultra-compact USB 2.0 Wi-Fi adapter for connecting personal computers, HTPC systems and laptops to home/office/public Wi-Fi 4 (802.11n) wireless networks. One of the most affordable and popular models in the base price category of 2019. Differs in the smallest possible dimensions and low weight, which is important for operation in tandem with small-sized mobile computers. When connected to a laptop / ultrabook, it almost does not protrude from the size of the device, so it does not require dismantling when transporting a computer in a bag or backpack.

The D-Link DWA-121 Wi-Fi adapter has one built-in 2dBi antenna and is compatible with a wide range of 802.11n network devices. According to the manufacturer, it provides wireless data transmission in the 2.4 GHz band with a peak speed of up to 150 Mbps. The actual maximum connection speed at a small distance from the router / access point does not exceed 100 Mbps. This is quite enough for flawlessly fast surfing, cloud services and web applications, gaming, watching FullHD-quality streaming video, video conferencing and other popular household or office tasks.
