DHCP problems
DHCP problems
I've encountered issues with my modem assigning just one IP address. Spectrum explained that since I'm not using wireless services, it limits the modem to one IP and suggests adding a router with DHCP capabilities. I connected my old Buffalo DDWRT router, turned off Wi-Fi, and reset both devices. Now my PC gets internet but my Wi-Fi isn't working. Any advice on resolving the DHCP problem? I've already performed a factory reset on the router.
I checked the Google Wi-Fi setup page and noticed the same problem persists. Only one device can get an IP address, even though the router appears to have a signal.
Google WiFi functions as a router, so you don’t require the buffalo router. Link the primary Google WiFi unit (the one with the router part) to the modem. Make sure NAT is activated. This isn’t a DHCP problem, but rather a NAT concern.
Link the modem to the WAN port of your Google Wi-Fi router (the one with the globe symbol). If you have multiple RJ-45 ports, connect a cable from the Google Wi-Fi LAN port to another LAN port on your router; keep the WAN port unused on your Buffalo router. Open your DD-WRT settings and turn off DHCP so your Google Wi-Fi router can serve as the DHCP server.
It's odd they mentioned dhcp features because most devices already have them turned on by default. Others suggest using the router and the Google Wi-Fi app instead.
I figured it out by checking online. Google Wi-Fi doesn’t work behind another router, so I connected it directly to the modem and then to the DD-WRT router. I had to turn off DHCP and switch it to bridge mode. It’s hard to locate that setting in the GUI, but I’m trying to set it up so all my other connections can link through it soon.
Currently, none of these settings make the router function as a bridge.
Are you aiming for the Buffalo router to function like a switch? Then set it up as a standard router from the options, connect it through LAN ports instead of WAN, turn off NAT and DHCP. Protocols like RIP2, OSPF, OLSR, and BGP are available, along with access point settings. Enable the access point mode if needed. This keeps LAN ports working while disabling NAT and DHCP. For wired connections, a switch is better—managing multiple routers on one subnet can become complicated.
