## Long description

EW-7811Un V2 is a nano USB wireless adapter that provides compact, high-speed wireless connectivity. Despite its small size, this USB adapter supports data rates up to 150 Mbps when paired with 802.11n devices, offering improved throughput and extended wireless range compared with 802.11g. The adapter is designed for easy use: plug it into a computer's USB port to add or upgrade wireless capability without affecting portability.
Advantages
The adapter follows IEEE 802.11b/g/n standards, increasing coverage and reducing dead spots compared to older 11g adapters. It includes Green WLAN energy-saving features that reduce power consumption by approximately 20–50% during idle and adapt power output based on distance and CPU load. Software support for Wi‑Fi Protected Setup (WPS) simplifies secure configuration, and a multi-language setup wizard (16 languages) guides installation. Its compact design is tailored for laptops and does not obstruct adjacent ports.
