Setup Wifi on Raspberry Pi

Using raspberian the Wifi setup for the Raspberry Pi is really easy. I had the Wifi stick connected while installing and found all drivers being there already.

lsusb showed

Bus 001 Device 004: ID 0846:9041 NetGear, Inc. WNA1000M 802.11bgn [Realtek RTL8188CUS]

and /etc/network/interfaces had

allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

So i created my WPA-Supplicant file using
wpa_passphrase

and pasted the output in /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
        ssid="ssid"
        psk=<myencryptedpassword>
}

after doing ifdown wlan0 && ifup wlan0 I was connected to my network!

Update:
If you want a static IP, you have to “tell it” WPA-Supplicant like this:
/etc/network/interfaces

allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

iface homewlan inet static
address 192.168.12.123
network 192.168.12.0
netmask 255.255.255.0
broadcast 192.168.12.255
gateway 192.168.12.200

/etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
        id_str="homewlan"
        ssid="ssid"
        psk=<myencryptedpassword>
}

Update:

According to this and this site, the chipset is able to create and AP. Just get hostapd and https://github.com/segersjens/RTL8188-hostapd/archive/v1.0.tar.gz
