Have bought the same 2 pieces of the TRENDnet TEW-684UB; Unfortunately, I can do what some have described with respect to the jiggling cable only confirm. And is it's up to the internally built Mini USB A socket in the housing of the Wirless N Adapter (Both). Processing quality so Poor. Installed on 2 computers, each with Win XP and Win 7. benefit of both frequencies to an adapter only about Trendnet software possible (not tried). Use the time 2.4GHz network, because by 2 walls (old building) and a distance of almost 8 m of Emnpfang in the 5 GHz network is significantly worse. Better reception in the 2.4 Ghz network than with FRITZ! WLAN USB Stick N 2.4 or Hama Wireless LAN USB 2.0 Stick 300 Mbps.
Conclusion: Due to the poor free processing Recommendation (attach cable with Kleband the housing to avoid wobbles) only with a fixed USB cable to operate - 3 stars from me because of that.
