ok, it shows up.
net.wlan.hwmp.inact: 5000
net.wlan.hwmp.rootconfint: 2000
net.wlan.hwmp.rannint: 1000
net.wlan.hwmp.rootint: 2000
net.wlan.hwmp.roottimeout: 5000
net.wlan.hwmp.net_diameter_traversal_time: 510
net.wlan.hwmp.maxpreq_retries: 30
net.wlan.hwmp.pathlifetime: 5000
net.wlan.hwmp.targetonly: 0
net.wlan.addba_maxtries: 3
net.wlan.addba_backoff: 10000
net.wlan.addba_timeout: 250
net.wlan.recv_bar: 1
net.wlan.mesh.maxholding: 2
net.wlan.mesh.maxretries: 2
net.wlan.mesh.backofftimeout: 5000
net.wlan.mesh.confirmtimeout: 40
net.wlan.mesh.holdingtimeout: 40
net.wlan.mesh.retrytimeout: 40
net.wlan.mesh.gateint: 10000
net.wlan.cac_timeout: 60
net.wlan.nol_timeout: 1800
net.wlan.devices: urtwn0

something must have changed in the startup, since I can not get wlan0 started.
i have
in /boot/loader.conf
wlan_xauth_load=“YES”

in /etc/rc.conf
wlans_urtwn0=wlan0
ifconfig_wlan0=“WPA SYNCDHCP”

cheers and season greetings
