Even here Authntication mode should be restricted!

Try using Authentication Mode Restricted.

Got no IP from the dhcp. Probably ue to authentication errors in your WLAN.

Should better state:
ra0 RT2500 Wireless ESSID:"Heimnetz" Nickname:"kirk"
           Mode:Managed Frequency=2.412 GHz Access Point: <some MAC
address>
           Bit Rate=54 Mb/s
           RTS thr:off Fragment thr:off
           Encryption key:<the key> Security mode:restricted
           Link Quality=71/100 Signal level:-195 dBm Noise level:-256 dBm
           Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
           Tx excessive retries:0 Invalid misc:0 Missed beacon:0

The difference is mainly the security mode!
