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: I'm not sure 'hate it' is right but after a lot of frustration attempting to make my Precision M6700 recognize the device (using Intel's drivers from their website) I was unsuccessful. I ended up returning to my older Wi-Fi adapter (another Intel adapter) which worked without incident. Bummer for me as I was looking forward to better stability and speeds.
Summary: Unfortunately I received a bum card that did not work at all. I was receiving Error Code (10) in device manager. I returned it and bought another one from a different vendor and it worked great!
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: Not really a big problem, just something to be aware of: This card does not do bluetooth as many other wireless cards do. Also be aware: That tinsy little picture -- That's more or less the card's actual size; it's like a postage stamp. You need two fully functional hands to deal with this baby. I had trouble installing it in my full-size tower unit, mostly because my hands don't work well anymore. Pair of hemostats came in very handy.
