Re: Redhat Linux Enterprise 6 On T520

run

# lspci 

# lsmod 

# rpm -qa wireless-tools

<and paste the output here>

 

Also - is there a config/startup script?

# /etc/sysconfig/network-scripts/ifup-wireless

 

i have heard of some devices having problems if you had disabled the WLAN in Windows and then rebooted in Linux.

 

If you do have a switch/button to enable the WLAN, what is dumped to /var/log/messages when you press the button?

If you do have a switch/button to enable the WLAN, what is dumped to /var/log/messages when you press the button?

 

No changes in the /var/messages..

 

I have the machine is dual booting for windows 7 and redhat linux 6 64bit.
