5 out of 5 eggsGreat Card with the Right Driver

Pros: I originally purchased this card because it was on sale and I needed a wireless N card for an older laptop that only had wireless G. The install was simple and straight forward (running on Windows 7) the drivers that came with the card and on DLinks website were horrible. I was only getting 7 Mbps at best most of the time. I discovered the manufacturer of the card is Realtek and downloaded the driver for RTL8188CUS (the part number for this card) and now I get 25 - 30 Mbps. I am using driver version 1021.3.0912.2012.

Cons: Very poor drivers for an otherwise great card.

Other Thoughts: The driver can be found at Search for RTL8188CUS in the download section.

1 out of 5 eggsHot garbage

Pros: Compact size.

Cons: Horrific performance. I had two G wireless adapters that vastly outperform it on two different computers.

Connection status reports 72Mbps, but reports less than 3 Mbps (on an 18 Mbps connection). File transfers between computers on the local network reflect that same sub 3Mbps speed.

Other Thoughts: What a piece of garbage. Tried the drivers on the disc (June 2010) and drivers directly from D-Link's website (August 2011). Same results either way on two different Windows 7 PCs.

1 out of 5 eggsDLink missed on this one.

Pros: The product was cheap, however a low price often indcates an inferior product. That axiom is certainly true in this case.

Cons: Windows 7 hates this device. Having installed on several computers, the driver is found and installed but the device does not activate until the DLink bloatware is installed.
Even then, it will not connect to a hidden SSID. It is possible we just got a bad batch (five of them) however it is more likely just a subpar product. Windows network and sharing center reports an "unknown error" when attempting to build a network connection.

Other Thoughts: Edimax has a nano adapter that installs first time every time.

4 out of 5 eggsIt works

Pros: *Appears to work better (stronger signal) than the D-Link DWA-556 Xtreme Desktop PCI Express card when installed approximately 6 inches from each other on the same desktop and alternately disabled in Device Manager.
*So far no excessive heating, only slightly warm to touch when removed.

Cons: Installation software did not automatically recognize the device and install the software. Called D-Link Tech Support. Had to install the driver using Device Manager and pointing to the location of the drivers. Operating system: W7 64 bit. This really was just a bit frustrating, the device worked fine after.

Other Thoughts: Also could not use the included CD because laptop does not have a working CD drive so copied CD contents to a flash drive and installed drivers from the flash drive.
