This card is mini pcie (express) not mini pci. A small quibble but it did cause me to waste time looking at it.

You’re right, my mistake.

This is a great explanation (exactly what I would have done), but I’m unable to find info on which pcie WiFi cards are compatible with C850. I want to install a 2400Mbps card, but uncertain if it will be compatible. Do you have any info/advice on this?
