I have an intergrated Intel (R) Pro\Wireless 3945ABG Network card installed in my Dell Inspiron 1720 laptop. I would like to upgrade the "g" capable card to an "n" capable card. Would some kind soul please inform me what card is required?
I recommend you review http://support.intel.com/support/wireless/wlan/sb/CS-031167.htm http://support.intel.com/support/wireless/wlan/sb/CS-031167.htm for information on possible issues when upgrading your adapter. You should also contact Dell for support on which cards are compatible with your specific system.
