Summary: The DWA-556 is a European model NOT covered by U.S. Tech support or warranty through D-Link. Spent hours on hold only to be advised this model is not supported! Vendor shipped product from the U.K. and box clearly states that warranty is not covered in the U.S. (See photo).
Summary: After an hour of trying to install the Cisco-Linksys Wireless-N PCI Adapter with Dual-Band(WMP600N) I called Cisco-Linksys. With NO help there! So I went to Fry's got a D-Link DWA-556 Xtreme N PCI-E & was up and running in 3 mins. All you hear about Linksys these days is how crappy they are.
Summary: Comments about D-link Xtreme N DWA-556 PCI Express Desktop Adapter: I'm using this DWA556 in my Dell Studio-XPS. This seems like the only game in town for a PCI Express x1 card. I first used an external USB wireless-G while waiting for this card to arrive. Took less than 10 minutes to install.
Pros: Easy To Setup, Fast Connection Speed, Reliable connection
Summary: Works fine with winxp 32bit and a d-link 2740r. I only run a type N network and this card picks up at full strenght through 2 brick walls with a distance of about 8-10m between pc and router and gives a link speed to the router of 270.0Mbps and has never droped a connection. Update....
Summary: For the Linux users out there in The Cloud, this D-Link pci-e wireless card works straight out of the box in 64-bit Ubuntu 10.10 (NDISwrapper not needed), and it delivers on its promises: no dropped connections, and increased linespeed as compared with its predecessor, a wireless G adapter.

Summary: Dont risk buying this card if you run win 7 / x64 bit. It may not work . It worked for a day for me then caused blue screens and couldnt boot pc. All MOBO PCIE BIOS settings were left in AUTO.
Summary: No complaints on this end. I see someone complaining about poor signal compared to laptop but I think that's more an issue with their wireless modem/router than this card. I had the same problem (due to my laptop having an in built booster!).
Summary: So before I received the card I was quite weary as to how well it would work with some of the negative reviews on here, soon as I got it I plugged it in, turned on my computer to find.... nothing. It wasn't detected.
Summary: received this card today , installed cards in there pcie slots on 2 systems ( windows 7 32 bit and windows 7 64 bit desktops ), both found drivers and installed without doing anything else ( did`nt even open the cd pack enclosed with card ), just entered wireless key and up and running ..
