【硬體】請問3com的無線網卡
 

請問一下，下面這兩章3com的無線網卡除價錢外有啥不同？

因為我搞了粉久還是霧煞煞.....><


我看規格上藍色的那塊是說當天線收入時會關閉網卡電源（Patented XJACK antenna with smart switch extends for excellent WLAN performance and conveniently retracts to activate power-save mode, preserve battery life, and protect the antenna）。
但綠色的那塊就沒有這樣寫了（Patented XJACK antenna extends for excellent wireless LAN performance, and retracts for safe travel and transport
），事實上綠色的也不會關閉電源。

不知有沒有人兩張都用過，可否分享一下心得？

感謝囉∼
