>Description:
Currently, if_urtw(4) driver for Realtek wireless NICs
supports only station and monitor modes.
I have a notebook with embedded USB wireless NIC supported with
this driver and was able to successfully setup it in ad-hoc mode
and in hostap mode (with and without hostapd) and connect
my Nokia E72 smartphone to the Internet over wifi using this notebook
after applying the following patch to the driver.
usbconfig shows me:
ugen7.2: <product 0x8189 vendor 0x0bda> at usbus7, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=ON
I've used standard instructions from the Handbook (never dealt
with Wifi devices before) and found no problems with one exception:
"ifconfig wlan0 scan" does not work but "ifconfig wlan0 list scan" does.
>How-To-Repeat:
Try to enable hostap/ad-hoc modes with if_urtw, it won't.
