Boost Your Wireless Reach
EW-7811UnV2 is a nano USB wireless adapter that supports maximum range and speed. Despite the size, this tiny USB adapter supports data rates of up to 150Mbps when connecting with wireless 802.11n devices which is 3 times faster than your typical 802.11g connection. Just plug it into computer's USB port and enjoy incredible high-speed wireless network access.
Robust Coverage
EW-7811UnV2 complies with wireless IEEE 802.11b/g/n standards. Built with the latest wireless technology, the EW-7811UnV2 can increase your wireless coverage up to 3 times as much and greatly help reduce "dead spots" compared to your 802.11g adapter. Data transmission rates can now reach up to 150Mbps when connected to a 802.11n network, with signal travel further and a lot more stable connection as compared to previous generation 802.11g networks.
Simply Sips Power
EW-7811UnV2 has adapted a clever protocol in smart transmission power control. The adapter smartly adjusts transmission output by distance and CPU offload to help reduce power consumption when wireless is idle. With the green WLAN technology, the power consumption can be reduced up to 20% ~ 50%.
Easy to Setup Wireless Security
Wi-Fi Protected Setup (WPS) is a standard for an easy and secure establishment of a wireless network. This wireless USB adapter supports software WPS-compatible configuration. By pressing 2 buttons, your wireless network is immediately secured providing your wireless router also supports this function.
Multi-language EZmax Setup Wizard
The included 16 languages EZmax setup wizard and friendly UI will walk you through configuring EW-7811UnV2 to your wireless network.
Portable and Compact Design
Best of all, the EW-7811UnV2 is currently the smallest wireless adapter on the market. The compact design of EW-7811UnV2 is convenient to carry for all mobile users. It also means you won't accidentally snap your USB adapter anymore and it is barely noticeable once plugged into the USB port.
