[Solved] RB 5009 ROS 7.1rc5: Ether-1 doesn't receive IP Adress via DHCP

Solved by installing rc6

Hello,

i just received my RB 5009 router (ROS 7.0.x.)
I started it up, with WAN attached to Ether-1 and ran the default config script.
DHCP client is enabled on Ether-1 and link is on.
However i do not receive an IP Adress or a DNS. DHCP client keeps in searching… state.
Updating to 7.1rc5 didn’t change anything.

I’m running an RB 4011 (ROS 6.49) in exactly this configuration without any problems.
What am i missing?

Thanks!
