Hello
I'm trying to run RTL8192DE-based wifi module in AP mode using hostapd.
RTL8192DE is connected to Marvell Kirkwood CPU using PCI Express bus.
But the kernel hangs right after hostapd was started.
In STA mode it is possible to scan for networks in 2.4 GHz band and it
discovers ~10 APs.
Was rtlwifi driver tested to work with hostapd?
I've tried compat-wireless-2011-12-01 and
92ce_se_de_linux_mac80211_0005.1230.2011.tar.gz from Realtek site.

without knowing any details of the kernel hangs, it is impossible to know what
might be wrong. If you switch to the logging console immediately upon starting
hostapd, is anything reported on the screen?
I have not used the RTL8192DE as an AP, but the SE variety does work. There are
some important fixes for AP mode that are not in compat-wireless as old as the
one you are using. Please try a version from this week. Those fixes are also not
included in the driver on the Realtek site.
What kernel version are you using? Is there a possibility to switch to the
kernel from the wireless-testing git tree?

I'm using 2.6.37 which is in OpenWRT's trunk for kirkwood platform.
I've compiled compat-wireless-2012-04-17 and now RTL8192DE doesn't
hang during hostapd start.
But the AP can't be found during scan performed on PC.

Also I've tried to install RTL8192CE into the same board and it worked
well in AP mode, so I managed to connect to it.
