Summary: This wireless card is great! The ultimate N 633 was quite easy to install and I only need to install a new wifi driver from intel to get the card going. For context, I previously had a stock 2012 x51. The card that it came with would usually only give me 4 bars at most and didn't always hold a steady connection; that situation certainly wasn't good if you're a gamer.
Summary: After 3 months of ownership of this card I am now updating my rating and comments on it because I found the solution to the card's problem with being slow to connect. I had previously stated that it was intermittently slow to connect and occasionally would drop the connection. I observed that there were also numerous other, similar complaints on the internet about this device with no solutions in sight as yet.
Summary: I use this for my Media Center running Linux. This device has been supported since at least Linux 2.6 and it works well for me -- OpenELEC recognizes it with no fanfare. I can stream HD content from my network easily whereas my previous 150Mb/Sec unit sputtered and re-buffered when playing high bit rate content.
Summary: I bought this card together with a half - to full-height adapter Half to Full Height Mini PCI Express(PCI-E) Card Bracket Adapter for a 2007 Lenovo T61 14.1-inch widescreen laptop after I flashed the BIOS to Middleton's 2.29-1.08 to get around the whitelist problem. As I feared, the antenna wires were too short to reach the card so I took what I could get, reversing connections of the grey and black wires (no white wire on my T61).
Summary: This adapter definitely gave me the ability to connect to dual band wireless connections. My Lenovo Y500 laptop, however, has a blacklist enabled in the BIOS, so I had to go to the extremity of finding a BIOS crack.
Summary: My wife's dell 17R is great except the wireless stunk from day 1. It had the Intel 1030 wireless/bluetooth adapter which had spotty connections, sometimes just slow, sometimes would not connect at all despite a ipad right next to it connecting fast, and mediocre range. For a fast machine (I put in an SSD, 8GB RAM, good processor for what she does) the wireless was just really frustrating and a dealbreaker. After doing my research I bought this 6300 card.
