I have Chrubuntu installed on an Acer Chromebook 13 and would like to connect to my home wireless network. I was able identify the card with iwconfig and make sure the network is reachable with iwlist mlan0 scan.

I then followed the instructions at the Wiki to connect:

$ iwconfig mlan0 mode managed
$ iwconfig mlan0 channel 11
$ iwconfig mlan0 essid 8ef11c

None of these commands returns errors message, however, when I try to set the password I get this back:

$ sudo iwconfig mlan0 key s:999999999
Error for wireless request "Set Encode" (8B2A):
    SET failed on device mlan0 ; Invalid argument.

After that any attempt to connect returns the usual:

connect: Network is unreachable

Any hints on what I may be doing wrong?

Update: Answering the request from Pilot6:

$ lspci -knn | grep Net -A2
pcilib: Cannot open /proc/bus/pci
lspci: Cannot find any working access method.

Please [edit] your question and add output of `lspci -knn | grep Net -A2` terminal command. – Pilot6 Oct 26 '15 at 16:19
According to the documentation, the encryption is done like `sudo iwconfig mlan0 key s:999999999` – Terrance Oct 26 '15 at 16:24
The `key` argument was missing, I have to copy this by hand from the chromebook screen. – Luís de Sousa Oct 27 '15 at 08:21
