How do I find out what driver I need to configure my wireless card?
I am running ghostbsd 2.5 on an Asus One 722.
Thank you.

Use pciconf and usbconfig and kldstat and uname commands

How do I find out what driver I need? Here is a stab at answering this question
List the PCI Bus Devices operating in your hardware.. The RealTek RTL8188CE is what I am working to make operational in GhostBSD. It does work as of January 11, 2017 with FreeBSD 12.0 Current Revision greater than R307529 Note that in FreeBSD 12.0 Current revision 307529, the driver was rewritten where the RTL8192CU USB & RTL8188CE PCI Realtek Wi-Fi were combined into one driver if_rtwn with a USB interface if_rtwn_pci.ko and a PCI interface if_rtwn_pci.ko kernel modules. At this time the if_urtwn.ko kernel module is deprecated after revision R307529. Before this revision, use the if_urtwn.ko file with the RTL8192CU USB device driver with products like Edimax EW-7811un.
Device driver interface if_rtwn.ko and a PCI interface if_rtwn_pci.ko kernel modules

Code: Select all
 sudo pciconf -lv

If you have to load kernel modules, use the kldload command.
Code: Select all
kldload if_rtwn_pci.ko if_rtwn.ko

or
Code: Select all
kldload if_rtwn_usb.ko if_rtwn.ko

or for older FreeBSD before revision r307529, use
Code: Select all
kldload if_urtwn.ko

What version of GhostBSD or FreeBSD are you currently running? Is the device driver you need, functional with this release version of FreeBSD? r310386M
Code: Select all
uname -a

fred@kliktel ~> uname -a
