I bought this adapter without an antenna for my mother's computer as it tends to tip over and hit objects and I was afraid the antenna would break. As I expected, the signal is a bit weaker than what I got with Antenna Warmstor USB Wifi Adapter AC600Mbps Wireless Wifi Card 802.11ac Dual Band 2.4G/5G Network Adapter with Antenna for PC Desktop Notebook Tablet, Support Windows 10/8.1/ 8/7/XP/Vista, MAC OS X 10.4-10.12, but for some reason this gives me faster speeds (which I wasn't expecting). So if you are not far away this is ideal. I got mine about 36 feet from my router. With two walls (also called space) between the room where I installed it. And as you can see in the video and screenshot, I'm getting more than reasonable speeds.
