Re: R8500 DHCP not working

Guimar · ‎2019-06-23

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).
