150M无线网卡 黑白双煞 （巨便宜）

3070 无线网卡专为高要求用户设计，并且内置了智能天线，不仅速度快，而且抗干扰能力强，传输稳定，速度可达150Mbps，能够让用户流畅、快速的进行网页浏览、在线收看等活动。

3070 具有优先级服务功能，确保视频、语音等带宽敏感数据的优先处理，让用户流畅的进行视频通话等活动，确保了重要任务不受影响。它还支持64/128/152 位WEP加密，WPA/WPA2、WPA-PSK/WPA2-PSK等高级加密与安全机制，以多种方式保护网络安全。

芯片是台湾雷凌RT3070,比realtek 8188芯片强很多了，RALINK是最早投入研究11N的芯片供应商之一，比realtek要早很多。8188芯片比传统的54M还要便宜，但是有一些缺陷，比如用的时间长了就死机等等。

目前的11N芯片之中，还是RT3070比较不错。市场认可度！
