Summary: Just to test that it can work poroperly I basically had to put my desktop computer right next to the router just to get it up to speed. Putting my computer in the next room and the signal becomes slow and unreliable.
Summary: Just bought one for my desktop PC. Signal strength good but nowhere near 300 mbps. Signal strength is constant, though, which is good. Good use for first day, will see how it performs in the future. Position is one ceiling away from the router so range is not an issue for me.
Pros: Easy set up, good signal strength, size not a problem for me. No trouble finding wireless network.
Cons: Trivial issue: will not automatically install driver, needs driver CD, requires system restart. Signal strength constant at 135 mbps, not 300 mbps.
Summary: bought this for a pc that is located at the other end of the house, picks up the signal fine, about a consistent 40% but the good thing is that it has yet to drop signal or not find my router like other wifi adapters i have tried. would buy again when it's back on sale.
Pros: Works fine, found router on first try. easy installation.
Cons: signal strength gets a bit weak compared to some better wifi adapters.
Summary: Had to reinstall my system and plugged it into the USB slot again but the drivers didn't install automatically. Not really a complaint since it comes with a small disc with drivers on that so it was still quite easy to install. Excellent buy.
Pros: Works awesomely
Cons: Drivers only seemed to plug-and-install once
