Having trouble with r8712u, I heard this was the best place to ask...
> CONFIG_R8712_AP: This option allows the Realtek RTL8712 USB device to be
an Access Point.
I've enabled this option, and built r8712u as a module, but I can't seem
to set the essid. I can't get the command "iwconfig wlan0 essid
<whatever>"
to work.
Here follows a log from my testing:

I understand this is a staging driver, just added from realtek's driver
base, but I can only get it to work as a normal client using
wpa_supplicant. My distant goal would be to use the card as an access
point, but for me to do so, I think I must be able to use iwconfig...
Hope someone can point me in the right direction!
