I am new to Debian (previously using Ubuntu, which is also Debian based). When I installed it on my Lenovo G450 laptop, I skipped the wireless configuration (I really didn't know how to do that).
After the installation, I found no wireless network available.
I add
iface wlan0 inet dhcp
to /etc/network/interface
, then typed
iwlist wlan0 scan
But the terminal told me that "interface not support for this operation".
Anyway I tried
iwconfig wlan0 essid xxx key xxx
and the terminal said: "invalid argument".
Can anyone help? I had to turn to Fedora/Ubuntu again. They have network-manager
to configure the wireless network, but Debian does not. I wanted to install network-manager
, but I can't connect to the internet.

. — As for your question: Are you sure you added it to/etc/network/interfaces
and notinterface
(notice the missing "s")? Have you done a/etc/init.d/networking restart
after editing the interfaces? And "interface not support … " – are you sure this is the exact error message you get?/etc/network/interfaces
needs aniface
, not ´interface` line where you put thewlan0
.
