I love this little guy. It seems to be the same as others from different sellers that cost around $17 but was $13 when I first thought about ordering. I would like to mention that this seller offers a shorter warranty but it would be the deal of the century if I ordered then, especially compared to more expensive adapters with the same characteristics and I believe the same internal components. On an Ethernet-connected laptop in a room with an AC router, download speeds average 73 Mbps. In a room across the house, this adapter boosted speeds to an average of 71 in the 5GB space. Speeds with the laptop's built-in adapter averaged less than 20Mbps using 3 different speed test sites. I bought the adapter for $15 from seller Zhiyun Gimbals and it has since gone up again ($16). If the price goes down, I'll buy a few more. Highly recommended if you have a router that can take advantage of this. Please note that the internal adapter has priority during installation and must be disabled while it is enabled. The installation was plug and play in W10 on several laptops. A detachable antenna is simply necessary in the back room, but it is not needed next to the router. Also note that the 2.4GHz band is much slower in my situation. Performance varies by router and location. I will mention 2 other adapters I tried. Ordered Neoteck Gold Pro AC 5G 600Mbps Wireless USB Adapter Dual Band USB WiFi 802.11 AC/B/G/N Max Speed up to 5G 433Mbps 2.4G 150Mbps Support Mac Windows 10 Windows 8 7 Vista XP at cheaper price ($13) . It used the same driver but didn't work well so I returned it. I also bought AC600Mbps WiFi Dongle, EDUP N600Mbps Dual Band Wireless USB Adapter 5GHz & 2.4GHz (433Mbps/150Mbps) WiFi Dongle for Win 10/8.1/8/7/XP/Vista/Mac OS10.6-10.12 (Pink) (15th $). ) because I need a smaller laptop dongle that I regularly slip into my carrying case and leave the adapter in. It works very well even without an external antenna, although I didn't test it in a room away from the router. . However, I conclude from a small sample that EDUP makes well working adapters.
