I am trying to connect my RPi to my WLAN, but I fail. The network connection works when I use a cable. The RPi was bought about two weeks ago, and I am using a recent (I don't know exactly which) version of Raspbian.
My router is an AVM Fritzbox 7270 running a WPA/WPA2-secured wireless network with a public SSID and DHCP enabled. The network key is a number with 16 digits.
The wireless network is found if I type
iwlist wlan0 scan. The wireless network adapter being used is a Netgear WNA1000M. The adapter is listed if I type
ifconfig, but it has no IP address assigned.
I updated the
/etc/network/interfaces file according to the information I found on the web. Now the file looks like this:
auto lo iface lo inet loopback iface eth0 inet dhcp auto wlan0 allow-hotplug wlan0 iface wlan0 inet dhcp wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf wpa-ssid MYSSID wpa-psk MYPSK iface default inet dhcp
MYPSK I entered the SSID of my network (without quotes) and the value I got from the
wpa_passphrase command (also without quotes).
The file looked originally like this:
auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp
When I reboot my RPi, the blue led of the wireless adapter flashes for about one second, then turns off again, and I can not access my RPi in a wireless way.
Once I connect it to the cable, I am able to access it using SSH again.

As you can see the wireless adapter is being detected in the lines that start with
usb 1-1.3, but nothing happens afterwards.
The RPi is powered by an adapter with (I guess) 1.0A, it may be 2.0A.
Any idea what I am doing wrong?
