Summary: Great product. Prior to my purchase of this antenna I was unable to gain a signal on my laptop from the first floor to the opposite side of the house and second floor where my router is located. I'm now able to receive an "excellent" signal rating.
Summary: I am very pleased with the D-Link 6dB1 Antenna. It was very easy to install and has increased my connectivity to my wireless router. With the antenna on my PC wireless card I would get between 3 and 4 bars and would lose the connection but now I am at a constant 5 bars.
Summary: Didn't do the trick for me. I was trying to go through a couple of plaster-and-lathe walls, which may be too much to ask, but even then it was less effective than the stock antenna. Plus, it comes in blisterpack packaging = impossible to return. :( YMMV.
Summary: Returning this antenana because the performance was actually worse than the tiny standard Apple G5 antenna with its theoretically less advantaged placement under a desk. Mac Stumbler rates the signal strength around 45-51 with the standard T shaped antenna. Even raising the DWL-M60AT to head height the signal strength never rose over 43%.
Summary: I connected this to a linksys Wireless G with speedbooster pci card and went from 4 bars of reception to 5 bars and sometimes it will go up and down from 3 to 4 but for the most part it stays at 5 bars. Not sure if its really worth spending over $30 with the shipping for it though.
