>Description:
I bought a wlan adapter for my TV.
I tried it under FreeBSD, but it couldn't recognise it.
So I made my homework, and here is the output.
It is a "Samsung WIS09ABGN Wireless LAN Adapter".
It has Ralink chipset in it, so the if_run and runfw
drivers should work with it.
Here is the info and the usbconfig outputs:
Name: Samsung Wireless LAN Adapter WIS09ABGN (for selected 2009-2011 models of
Samsung TVs & Blu-Ray Players)
Model: WIS09ABGN
Model Code: WIS09ABGNX/XEC
it should work - and it works! - with the if_run & runfw drivers

===
This output is with the original if_run and runfw modules.
After it, I made two small changes in the src:
a) added the device info into /usr/src/sys/dev/usb/usbdevs file:
product SAMSUNG WIS09ABGN 0x2018 WIS09ABGN Wireless LAN adapter
b) and added it to the known list of HWs in the
/usr/src/sys/dev/usb/wlan/if_run.c file:
RUN_DEV(SAMSUNG,WIS09ABGN),
unloading the original module, generating the new (with
cd /usrs/src/sys/modules/usb/run
make
commands) and loading it with:
kldload runfw
kldload ./if_run.ko
and voila, the system has a new run0 interface. After it, created the wlan0
interface, started wpa_supplicant and dhclient, and I have a working wifi
connection.
usbconfig -d 2.2 - with the "modified" driver
ugen2.2: <802.11 n WLAN Ralink> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps)
pwr=ON
It is on FreeBSD 8.2-p3 i386.
>How-To-Repeat:
Buy a Samsung-TV wifi dongle, and try it under FreeBSD.
>Fix:
Put the
product SAMSUNG WIS09ABGN 0x2018 WIS09ABGN Wireless LAN adapter
line into usbdevs, and the
RUN_DEV(SAMSUNG,WIS09ABGN),
line into if_run.c. After it, it should work.
