urtwn driver for Edimax EW-7822U WLAN nano USB AdapterJulian H. Stacey jhs at berklix.comWed Oct 2 23:58:25 UTC 2013
Hi current@,
It seems I need if_urtwn driver for a really miniature WLAN USB stick,
& if_urtwn is only in current ?
man 4 if_urtwn refers to ports/net/urtwn-firmware-kmod which is missing ?
It took hours to search this far, is there a quicker way to find
drivers that I should have taken, that could go as tips in
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-wireless.html
This is how I deduced what I needed:

I have the same wifi dongle, Edimax EW-7811Un . The Linux
kernel driver provided is RTL8192cu. It does not work
properly. However, a working driver can be downloaded from
Realtek: 8192cu. I'm using it now on my desktop with kernel
3.20.25, Ubuntu 12.04. Has worked fine with different
distros, various kernels
Instructions here:
http://www.linux-hardware-guide.com/2012-10-07-edimax-ew-7811un-wireless-usb-150-mbits-802-11n
http://www.linux-hardware-guide.com/2012-10-07-edimax-ew-7811un-wireless-usb-150-mbits-802-11n
The following devices are identical to the Edimax EW-7811UN:
* Edimax EW-7811GLn, EW-7811Un, EW-7811UWn, GWU-H811GLn
* Airlink101 AWLL5088
* Sitecom WL-365
* GETNET GN-521U
The USB stick uses the Realtek RTL8188CUS chipset, which
is supported by the kernel module rtl8192cu. This module
is included in the kernel since version >= 3.0 and will be
loaded automatically:
If the EW-7811UN stick is used with older distributions it
might be necessary to use the Edimax original drivers
together with NdisWrapper. Furthermore, one can use the
original Realtek drivers.

Seems for an older Linux than above, Also for 8192CU not 8192xC_USB, whatever the diference.

So I need urtwn, not in

So I need to jump from my 9.1 [via 9.2] to current src/
http://www.freebsd.org/cgi/ports.cgi?query=urtwn-firmware-kmod&stype=all
Fails, not there.
Maybe urtwn shares a BLOB from rsu ?
