Works well if AP/Router is in the same room. Not for long range.

Summary: The sensitivity of this wireless card is not great. There is no range. The wifi is stable with no dropouts.This card might be 600mw on the tx (transmit power), however the rx ( reception sensitivity) is really bad. Even with a high gain antenna the long range reception performance is terrible. It will show excellent when connected but your connection will be slow and have lags.
Range is limited - not the higher speed I expected.

Summary: The antenna is not good (too short?) and range is therefor limited. This device worked but was slower than the card I replaced. I have now gone back to my old card. There must be better cards than this one.
Summary: Decent card. Every once in a while it loses my Wifi connection. But I can't even say for sure that my card is to blame. So let's say I am a lot more happy with it than I am unhappy with it. Good purchase.
Strong transmitter but needs a higher gain antenna for good receive sensitivity

Summary: This card differs from basic wireless g adapter cards in two ways. First it is super g which combines two channels for a theoretical (but hard to obtain) maximum data transfer of 108Mbps when used with a super g wireless router. Second, and more important, at 600mWatts, it has an available transmit power significantly higher than most cards. At 54Mbps, it has a typical available transmit power of 22dBm vs. 13 to 15dBm for most cards. This is 22 vs.
Summary: I originally bought this to increase the reception for my computer in the farthest room from the router. There would be times that web pages would not load at all for about 30 seconds. So I replaced the wireless card with this one, hoping to fix this issue. There are still times that I'll lose the ability to load a page, but they are much less often, and for much shorter periods of time. I have a very good router, and my laptop picks up in the room just fine.
