zich6,   I had a small issue with this adapter and have corrected the problem.   Make a system restore point. That way if you have any problems, you can come back to what you have.   Download the Intel(R) Centrino(R) Advanced-N 6200 AGN drivers from Drivers & Downloads (drivers may say that they are Intel Centrino Ultimate-N 6300)   Save the drivers to your desktop.   Start, control panel, device manager, network. Right click on the Intel(R) Centrino(R) Advanced-N 6200 AGN, then click on remove. Tell it to remove the drivers, also.   Restart your computer.   Install the drivers your saved to the desktop.   Also try reading... Power Save Polling (PSP) causes connection issues with some access points      Rick
Just upgraded from the base card to a Intel Centrino 622ANHMW 6200 wireless half mini card.  The added speed is great, but the 1750 is locking up frequently.  I installed the recommended drivers and install went fine. Is there something like a setting I missed? Thanks.
