25.1.10 => 25.1.11: DHCP on WAN interface fails

[JanOsch]

Hi,

since updating to 25.1.11 (coming from 25.1.10) i'm not getting an ip address on one of my WAN interfaces anymore:
(This is a cable modem connecting, running in bridge mode, worked fine for months)

Deleted the interface completely, rebooted, added it again but still no joy. Disabled DHCPv6, makes no difference.

Any hints how to solve this would be highly appreciated.

Kind regards

Hey,

I'm not clear if you've rebooted just the router or the router and the cablemodem. For Cox in NV, you MUST power cycle the cablemodem if there is a hardware change (I'm guessing an update to the router's MAC address in the cablemodem?). Did you change any hardware or the assigned interface?
