I'm facing a problem that's about to drive me crazy. I'm running a Debian Linux distribution and currently trying to establish a connection to my wireless network (WPA2 security, wpa_supplicant already installed). The wireless dongle connects to the network, but it only responds to pings and lets me connect through SSH from another computer when the ethernet cable is plugged in. It is still reachable via wireless connection after unplugging the ethernet connection, but it won't work until a connection to a wired network had been created. I'm not sure if anything's wrong with my configuration here...
Output of 'ifconfig wlan0':
