Hi, The motherboard of Optiplex 755 mintower has 2 PCI slots. As shown in the picture below: [IMAGE] Wireless LAN PCI 802.11 b/g adapter WN5301A card is compatible on your computer provided if there are any free PCI slots. Also, providing the user guide’s link for your reference, the image of the motherboard is on page 32: [URL] Kindly get back if there are any further queries.
I am wanting to move an existing wireless LAN PCI 802.11 b/g adapter WN5301A card from another tower computer into my Optiplex 755 mintower.  Is this compatible, or do I need to get a different wireless card?  Thanks for your help.
