On Ubuntu (dapper at least) WEP is installed but not WPA (wi-fi protected access) a safer encription protocol. Wep can be cracked within minutes. To enable WPA you must:

1. Install wpasupplicant

# sudo apt-get install wpasupplicant

2. Generate wpa passphrase

# sudo wpa_passphrase ssid [passprase]

3. Add network info to /etc/supplicant.conf

network={
ssid="ssid”
scan_ssid=1 # only needed if your access point uses a hidden ssid
proto=WPA
key_mgmt=WPA-PSK
psk=123456a123456e34d67daef00eb5fab3ae228716e1e123456c004bc61dccc98c
}

4. Finally update network file /etc/network/interfaces
• Before

auto eth1
iface eth1 inet dhcp

• After

auto eth1
iface eth1 inet dhcp
wireless-essid MyWireless
pre-up wpa_supplicant -Bw -Dwext -ieth1 -c/etc/wpa_supplicant.conf
post-down killall -q wpa_supplicant

On Ubuntu (and in general) ntfs mount with write permissons is still a big issue. Here is a simple cookbook for NTFS read/write:

1. Add the folowing line to your sources.list file

# deb http://flomertens.keo.in/ubuntu/ dapper main

2. Add the repository key be able to download the packages

# wget http://flomertens.keo.in/ubuntu/givre_key.asc -O- | sudo apt-key add -

# sudo apt-get && sudo apt-get upgrade

3. Install the package

# sudo apt-get install ntfs-3g

4. Add your ntfs partition

# sudo pico fstab

/dev/partition /media/mount_point ntfs-3g defaults,utf8 0 0

Voilá mount or remount the drive and you have a ntfs partition writable. valid also for future removable ntfs drives.
