To make this notebook work in different departments, I need to use DHCP. At the moment I have to set the mtu manually, disbaling and reenabling the NIC (ifconfig re0 down, ifconfig re0 mtu xxxx, ifconfig re0 up). This seems to be strange. After that, the NIC seems to work as expected and the Laptop has connection.
