Input:
I wrote a review about this product a year ago complaining about not getting good and reliable wireless connection because the antenna was in the back of the card and hence, shielded by the metal case of a PC. The connection would work most of the  time but slow. What's most annoying was any minor change in the environment, say a person stay close by or humidity change, would make the card lose connection because signal strength was not strong and link quality was not good to begin with.
I had been searching for an external antenna to solve this problem since. Did not find any here or at any of the local electronic stores. Now the search is finally over. I just bought a TrendNet IA040 ominidirectional antenna that has a 3.3 ft cable that can be connected to the antenna connector of this card.
What a day and night difference. I can now download at the full 3 Mbps speed promised by my cable ISP through this wireless card with the TrendNet antenna. For those of you who have been struggling with the range and link quality of this card because of its bad antenna design, an external antenna is definitely worth it
