What are the best settings for a wireless PCI card?



Have you ran speedtest? Do you have another device you can run speedtest on as well?
 
Enable the top 3 options. Then run speedtest: http://www.speedtest.net/

If your speed isn't good after that, then it may be that where your antennas are (the back of your pc) isn't a good reception area. Turn your PC around and see how it does on speed test. If it improves a good deal, then you will need antenna extenders like the ones below to raise your signal up higher.

so disable everything else?
 


Leave the IEEE and radio on/off to their defaults, but turn off the multimedia/gaming environment and the power saving one.
 


Well try the settings thing I just posted and if the same result is achieved, then try the turning your pc around thing. Then you will know if you just need antenna extenders.
 


Don't move the GPU. The higher up slot is always the best one for your GPU and the fastest slot on the board. The wireless card's location in the motherboard won't affect it's speed. Mine is in the lowermost slot and runs great.

Give rosewill tech support a call, you might have a defective card.
