Acer Aspire One D257 w/ 10.04 Lucid: Wi-Fi disabled

[Rafu]

My girlfriend was bought by her mom an Acer Aspire One D257 netbook, which comes with Windows 7.
We installed Ubuntu 10.04 LTS Lucid (which is what we use on all our computers) on it, as a dual-boot option. However, Wi-Fi is disabled by default and it's not possible to turn it on via keyboard shortcut. We're apparently not tech-savvy enough to have a clue what to do.
Wi-Fi appears to work normally when booting with Windows, but no way we're connecting a Windows system to the Internet (and risk an epidemic of malware)! When booting with Ubuntu, ethernet cable connection works fine and we've been using it to update the system sometimes.

Download this

right click and open with gdebi
then reboot and see if it works.

[Rafu]

then reboot and see if it works.

It doesn't appear to work.

[unevenflow]

Please try in terminal

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

[Rafu]

Please try in terminal

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

First command echoes:

options iwlwifi 11n_disable=1

(no further result).

Both second and third command result in this output:

FATAL: Module iwlwifi not found.

I have no idea what that means, of course. Do you?

[gleble]

I have the same problem with a new install of 10.04 on an Acer one happy
I followed all the steps above an end up with this
FATAL: Module iwlwifi not found.
Does anyone understand/know how to fix this.
