Summary: I have had mine for over a year and it works. Set in wireless N mode my average signal strength is 29-34% at 25' 1 floor and 1 wall away from router. The average link speed using wireless N is 39mbps. When playing games online the connection will drop frequently.
Summary: Overall, the signal is quite strong (router to antenna distance is approximately 20m, same floor, through several walls). On average I get signals of approximately 80%. I haven't been able to use the wifi on the desktop however due to the extreme amount of interference that goes on under the desk (limited space, powerbars and wires running everywhere). However, definitely a good buy if you have a clean floor/working area!
Pros: Good range, Fast connection
Cons: doesn't work with extreme amounts of interference (as with any other wireless antenna)
Summary: Well, it's cheap and it's fast. The only thing I haven't tested is local network transfer via wi-fi, but my internet connection is extremely fast so far - rivalling the wired connection I ran at my old home. Definitely recommend!
Pros: -Was an amazing 45% off in recent sale, -Very fast.
Cons: -No software tools but that could actually be a strength because some software tools can be very unnecessary.
Summary: My old one broke down and I ended up grabbing this one because of the three antennas. Surprisingly, it gives me the same signal as I had with my old card with just one antenna, not that that's a bad thing since I get a decent signal through 2 floors. I do notice it cutting out for a second every 10-30 seconds when I play games though, but I can live with that.
Summary: I got it to replace ASUS wifi adapter which was horrible , this one its much better , unfortunately there are G devices on my network so I cant test N speed but overall very good product. One more thing the device got recognized in Windows 7 as Ralink and CD drivers are too old go to http://www.ralinktech.com/ and download drivers from there
Pros: Works very well, good price , wifi N
Cons: signal is little weak but without interruptions , outdated drivers
