I read the other negative reviews, and didn't believe them due to the positive reviews this product had received. What a mistake!I've had a Linksys WRT54G router and a Linksys WPC54G PCMCIA card for over a year now, and I'm very happy with both of them. Only problem is that I don't get a great signal in my basement. I thought that this antenna would help, but I couldn't have been more wrong. See this Network Stumbler graph (http://suspended.net/images/higain.png). My signal actually decreased when using the "High Gain" antennas compared to the factory antennas.I'm going to return this item and stick with the stock antennas and maybe build a reflector like this one: http://www.freeantennas.com/prod01.htm
