Product information

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.

Key specifications

  • Wireless standard: IEEE 802.11b/g/n
  • Maximum data rate: up to 150 Mbps (when connected to 802.11n device)
  • Interface: USB (nano form factor)
  • Energy-saving: Green WLAN protocol (reduces power consumption by ~20–50% in idle)
  • Security setup: Software WPS (Wi‑Fi Protected Setup) supported
  • Setup utility: Multi-language easy setup wizard (16 languages)
  • Design: Compact nano adapter for laptops; minimal obstruction of other ports
  • Use case: Can be used as an embedded wireless solution for Industrial IoT integration

How to use

Insert the EW-7811Un V2 into an available USB port on your computer. Install the provided setup wizard and follow on-screen instructions to select your wireless network and enter the password; the wizard supports 16 languages. For quick secure setup, use the software WPS option if your router supports WPS. Once connected to an 802.11n access point, the adapter can reach up to 150 Mbps and will automatically apply energy-saving modes when idle.

Recommendations

For best performance, pair the EW-7811Un V2 with an 802.11n router and position the host device to minimize physical obstructions. Use the setup wizard to ensure the latest drivers and firmware are installed, and enable WPS on compatible routers only when in a secure environment.
