Model overview based on user reviews  
The Mercusys MW300UM Wi-Fi adapter is an affordable option, praised for its price and appearance. However, users have noted several drawbacks, including unstable speed, limited distance coverage, and occasional disconnections. The adapter struggles to achieve speeds over 100 Mbps, often delivering less than 50 Mbps, which may be insufficient for some users. Additionally, it overheats and requires drivers that are only available via disk, posing a challenge for those without a disk drive. While it may suffice for basic needs, those seeking a more reliable and robust connection might consider other options.

good, it’s not far from the PC and the router doesn’t see more than 100 Mbit per second, especially for less than 50 maximum, it’s normal for the decals to be dull and turns on by itself, but for its price 200 UAH gold
