first, I'm german but i hope i can express my problem good enough that you can help me.

I have 2 W-Lan-Adapter:

1. Internal Atheros Adapter of my Acer Aspire One D270
2. Alfa AWUS036H with Realtek 8187 Chipset.

All was fine, since i tried to install the newest Compat-Wireless-Driver, because the Alfa-Adapter won't connect
to any AP's.. Wheter WEP neither WPA/2. After installing the Compat Driver (Version 3.8-rc2), ifconfig didn't showed
any Wlan-Adapter anymore.. No wlan0, no wlan1, nothing!

Now i don't know where's the problem?!

The only thing i've noticed is the output of dmesg:

rtl8187: ieee80211 alloc failed
rtl8187: probe of 1-4:1.0 failed with error -12

and after "modprobe ath9k"

ath9k 0000:02:00.0: No memory for ieee80211_hw
ath9k 0000:02:00.0: PCI INT A disable

Hope you can understand my problem!
