Can anyone tell me what the WiFi card is used on the FitPC2i?

And is this a PCIe card??

This is a Ralink USB card

Can this be replaced Ralink be replaced with a different card??

If so will it accept a full size PCIe provided that the interface is USB2?

Thank you for your help

FitPC2i has no user available PCIe interface. If you want to replace the built in WiFi module, than you have to seek for the USB one. Please note: this steps will require FitPC2i's case opening, and will void your warranty.

Can you please provide some examples of compatible USB modules? Particularly with 5GHz band.
We have Intel 7260.HMWG.S available in our pc parts market. Will it work?

Intel 7260 mini PCIe module used in our IPC2 system. It is not suitable for fit-PC2i that uses other form factor. We don't have recommended modules list for fit-PC2i besides the one on web-site spec table.
