LAN not working on Lantiq Xway AR9 rev 1.2 (Fritz!Box 7320)

I don't get a LAN connection to the router. Only a few times it works.
It is installed as WISP (connecting to Telekom hotspot as client) and connecting to wifi named test works but not via LAN.
I tried it with the release and now with snapshot but without sucess.
