Works well, good speed, connected to a trendnet "N" router. The only thing that you should know is that it does not appear to be configurable using a "hidden" SSID. I had to broadcast the SSID, configure the card, ensure that the feature was active that tells the card to connect to the network even if it's not broadcasting, and then hid the SSID on my router. It's a big of a quirk, but easily worked around. The price can't be beat!

TRENDnet is right up there with the "big boys" so you really can't go wrong!

The CD was not necessary at all, Windows 7 (32bit) recognized it just fine on bootup. Just be sure to boot to an admin account the first time to avoid a possible "failure to start device" type message when the driver gets installed.

The settings in Device Manager for the device were very limited, and connection performance was not optimal. But the next day, Windows Update automatically found a newer driver, and it actually boosted the signal strength! According to Windows, I was always getting Fair before, but now it's always Good/Excellent. Very cool! Also, there are now more device settings in Device Manager, the most useful one being "Multimedia/Gaming Environment" that was Disabled by default, so I turned that on.

Update: After a few weeks use, I have found the previous driver version 3.x to maintain a more reliable connection speed than the latest driver version 5.x. For some reason with the 5.x driver, the connection speed would start off at 300 Mbps but constantly fall way down to like 5-13 Mbps after some time, sometimes coming back up, sometimes not. The 3.x driver seems to work better after rolling back to it. Everyone's mileage will certainly vary.

The card is easy to install and it was instantly recognized by Windows 7 which downloaded the drivers for the item. I did not even have to use the installation disk.

I take the claimed wireless speeds with a grain of salt because there are so many factors that will effect the speeds of uploads and downloads. I get a strong signal in the room next to the router with the card and have not had a dropped signal. I can surf the web and download files fairly quickly so I am happy which is what most people do with their PC anyway.

If you need to connect your PC wirelessly, I definitely would recommend it, especially if you have Windows 7 since it worked right out of the box for me.

This arrived at noon, and by 1215 installed software and hardware, on the network and internet. It couldn't have been any easier than this. Make sure user installs software first before installing card. Following directions, it went in fast and easy. This was the easiest install of a wireless network card in a long time - and I've had some real challenges with Belkin, Linksys and so forth.
This is also dual band 802.11G/N, solid connections to an Actontec PK5000 (2.4Ghz) and dual band Apple (5.0Ghz)Airport. Seamless connection on each network. I have two internet connections running on my desktop - a wired and wireless connection via DHCP. It's simple to switch without having to disconnect before connecting. This is an excellent card. I live in two story house, 2.4G is on the first floor (100% connection) without losing connectivity. Compared to overpriced cards of Linksys, or Belkin, price is right.

300Mbps. Yeah, that's what they put on the box. Getting that in actuality requires proper configuration of both adapter, router and software, but is attainable. I find the Windows software (for xp, at least) to be better than the supplied Wi-Fi connect software bundled with this device. Works well, connection is solid. (granted, its only about 15 feet away from router. can not vouch for further distances.)

There are three images for the product whenI ordered and as I type this review: two picture a unit with long antennas and the last, if you click to it, shows a unit with short antennas. I received the short antenna unit, which has poorer signal than a single-antenna unit I was trying to replace.

Additionally: the software included with this unit, while it does support Windows Vista, has not been optimized and still includes a (mandatory) very poor interface designed to run on top of the Windows XP wifi settings.

Overall, I would not recommend this unit to anyone.

I live on campus housing and so I am not allowed a router which would give me a better connection. I previously tried to get by with the USB wireless adapter for 8 bucks hoping to save money. It just didn't cut it. I was getting 20kbps no lie. Got this baby yesterday and got up to 7mbps downloading speed from the exact same location in my apartment. The range on this is very good, very simple installation, and well worth the money. If you are struggling with the signal strength and you want a better connection, go PCI and get yourself this item. Well worth it in every aspect. PCI components are even simple to install for those that don't know the insides of a computer.

I called tech support to try and get this issue fixed, but they kept giving me the runaround. Most users state that they get somewhere close to 300Mbps, but I'm not even close to that. Decent buy if you just need plain old wireless. Terrible ping for gaming as well.
