R8500 DHCP not working

My R8500 DHCP is being ignored, dhcp requests are beng sent to the cable  modem (subnet 192.168.15.xxx)

I ihave tried disabled and RIP_1 for the DCKP  protocol type.

RIP Direction is set to Both  (any other setting results in no internet) .

 

My guess is the router is sending dhcp requests to the cable modem (even if it responding).

 

Disturbingly devices that get DHCP from the cable modem don't show as connected devices even if directly connected to the R8500

 

R8500

Firmware Version 
V1.0.2.130

   Apply                Cancel    

 
Device Name
R8500
I

LAN TCP/IP Setup

P Address 10.0.0.1
IP Subnet Mask 10.0.0.0
 RIP Direction        Both          RIP Version  Disabled  or RIP_1 
 
 Use Router as DHCP Server Starting IP Address 10.0.0.2  Ending IP Address 10.0.0.159 
 
Address Reservation   # IP Address Device Name MAC Address   1 10.0.0.77 tuner 00:18:DD:31:19:66    
 
only recent change is added allow  internet ping (new ISP requires the setting to configure Router).
