HowTo setup Wifi Edimax EW-7811utn USB Dongle for GhostBSD 10.3 & 11.0

Note that in FreeBSD 12.0 Current revision 307529, the driver was rewritten where the USB & PCI Realtek Devices
where incorporated into one driver rtwn. Load kernel modules: if_rtwn.ko if_rtwn_usb.ko For RTL8188CE Load kernel module: if_rtwn_pci.ko

Here are some websites URL to read up on, to gain knowledge about wireless setup on FreeBSD.

I hope this helps you get Wi-Fi working with your GhostBSD /FreeBSD computer. Please comment and add corrections and suggestions to make this forum post better.
I don't know how the Networkmgr GUI Wi-Fi parts work from the desktop, but this setup seems to automatically connect with not much effort. Maybe click on the up/down arrows in the upper right hand corner gets Wi-Fi stuff started going for you. wb7odyfred I need to later add some graphical pictures of the desktop Wi-Fi setup configuration.



For FreeBSD 12.0 Current r307529 Mon Oct 17 20:38:24 2016 UTC Here are some information web URLS to look at.

#create rtwn0 device

Code: Select all

ifconfig wlan0 create wlandev rtwn0

#Bringing up will load the firmware automatically. Then scan for local WiFi access points.

Code: Select all

ifconfig wlan0 up scan

Now your wifi nano usb dongle or your internal wifi pci device should be operational.,

That should show the urtwn0 driver connected with the USB nano WiFi dongle Edimax EW-7811un

[ASX]

By June 9 should be released the first beta of FreeBSD 11.1.
It would be interesting to know if the updated urtwn driver has been backported to FreeBSD-11.1.

Here is some reading material that I wrote about setting up a manual connection to Wifi . Look at both forum posts. They are slightly different. You can learn from them both.
Edit 3 files /boot/loader.conf /etc/rc.conf /etc/wpa_supplicant.conf
wpa_supplicant -i wlan0 -B -c /etc/wpa_supplicant.conf
dhclient wlan0

NetworkMgr is the Eric Turgeon created Python application that does edit those 3 files and runs the wpa_supplicant and dhclient (or dhcpcd ) to make your wifi connection. please note: ifconfig_wlan0="WPA DHCP"; use for encrypted wifi signeals ; use ifconfig_wlan0_="DHCP" for open non-encrypted wifi signals. "WPA DHCP" will not connect with an open wifi access point. Took me a whole day of testing to figure out this little tid bit!
