Hi there,

i just bought an Alfa AWUS036NHR for testing.
It runs with the rtl8192cu driver.
I have a question because sometimes the wireless adapter dont shows 
any
networks no longer.
I have to reload the module an then its showing some networks.

In dmesg it shows:

[ 262.219575] ADDRCONF(NETDEV_UP): wlan1: link is not ready
[ 269.770133] ADDRCONF(NETDEV_UP): wlan1: link is not ready
[ 270.947047] ADDRCONF(NETDEV_UP): wlan1: link is not ready

For any further output please let me know.
A complete dmesg output can be seen here, because theres also a 
problem when
associating to a network:

What kernel? There are some problems with kernels prior to 3.1 in 
connecting to 802.11n networks, and also a problem in clearing the 
keys. Both of these problems are fixed in the latest compat-wireless.

Larry

Kernel is Linux C1 3.1.0-rc6linux-next1.01-next-20110919 #1 SMP Mon 
Sep 19 14:23:56 CEST 2011 x86_64 x86_64 x86_64 GNU/Linux
I tried to apply the latest compat-wireless but errors are the same.

Chiefdome
I tried at least wireless-next but the adapter isn't showing up.
Where to get more log files and stuff?
Isnt this adapter good supported by the rtl8192cu driver or where is the 
problem?

Kind Regards

Chiefdome
