BE85 constantly renewing WAN IP via DHCP

Model: Deco BE85

Hardware Version:

Firmware Version: 1.1.1

I have a DECO BE85 connected via WAN Ethernet using a dynamic IP connection.

I work for the ISP providing the WAN connectivity. I can see the DECO BE85 constantly going through the DHCP process in our server logs:

DHCPDISCOVER

DHCPOFFER from the server

DHCPREQUEST

DHCPACK

DHCPRELEASE

The above process repeats approximately every 6 seconds and is filling our DHCP server logs. The only client with this issue appears to be my home DECO.

I've seen a similar issue reported with another DECO model (X55) on the US forums. The fix was a beta firmware.

Is there a beta firmware I could try with this BE85 to see if it resolves this issue?
