Give the devices on the LAN a fixed IP-address.
I have Verizon FiOS service which uses a Verizon ActionTec router. Yesterday the 4 LAN ports of the router broke. When Verizon tests the router it responds properly and WiFi access works, but my home wired LAN is broken. The Verizon ONT is ok, so phone and cable are fine. Verizon is sending me a new router but it won't be here for a while.
Since I have 2 TiVo Mini's (which provide remote access to my TiVo Roamio over the LAN) I'd like to make the LAN work. When I run a PC browser or diagnostics on the TiVo's they show that DHCP is failing. I don't know if a DHCP problem is the root cause or just a symptom.
Since the Verizon router has poor WiFi performance, some time ago I installed an ASUS RT-66U router that is plugged into one of the Verizon router's LAN ports. None of the other Verizon router ports are used, rather all the home cabling goes through the ASUS router.
I'd think that the ASUS router would provide DHCP but it doesn't seem to be happening. When I look at the router configuration I see it's set to the default settings except that it's using subnet 2, which makes sense because the Verizon router uses 1. DHCP is enabled.
I'm way out of my depth here so I'd appreciate any help in getting my LAN running.
