Please help

Try (as user root):

ifconfig wlan0 up

before iwconfig command and see what happens.

I have tried what you stated

#ifconfig wlan0 up

no result, but from windows i can get ip address.

at boot time i found an error

"error for wireless request set mode 8B06

Hi soumalya,

what distro are you using?
You try to configure the wifi manually, but are you sure that you don't have another distro daemon that try to use the wifi at the same time?

Flavio

Sir

I am using centos.

Hi soumalya,

I don't know your CentOS configuration, but but are you sure that you don't have a CentOS daemon that try to use the wifi at the same time?
