I am using Lenovo ThinkPad Edge 14 0578

Well. I made a very stupid mistake such that many important packages are deleted (Cause cannot connect to network , weather wire or wireless). Therefore , I have no choice but to reinstall with the DVD.

When reinstalling, I pluged the LAN cable and it state it can access to network. However, after reinstall, wire connection is ok but wireless not.

With ifconfig wlan0 up

wlan0: ERROR while getting interface flags: No such device

And iwconfig

eth0      no wireless extensions.

lo        no wireless extensions.

But actually , the chip is exist.

Basically, this sounds like drivers/modules problems. You can use the following to determine which module is associated to your wireless component :

lspci -vvnn

Load this module :

modprobe [module name]

You can set loaded-on-boot modules in /etc/modules. Add your wireless module to this file, and reboot.

Concerning drivers, have a look here : http://wireless.kernel.org/en/users/Drivers/iwlwifi

Thanks. For module, I don't know about it. You give me hint for search about iwlwifi. I found this helped me (but replace compat-wireless to backports) –  Yeung Oct 3 '13 at 12:31
    
I run lspci -vvnn but I do not guess which module is associated to the wireless component. Which line specifies this information ? –  begueradj Jun 18 at 12:20
    
Search for words like "Wireless", "Network adapter", but avoid "Ethernet". Then, look at the line "Kernel modules" under it. –  John WH Smith Jun 18 at 12:56
