Router IP Setup Examples for OpenWrt Wi-Fi Extender
For each setup:
Main Router IP = IP of your current home/ISP router.
OpenWrt LAN IP = IP you assign to the OpenWrt device lan interface. Should be a different subnet.
OpenWrt WWAN IP = Static IP for OpenWrt to connect to the main router's Wi-Fi. Must not conflict with DHCP.
Temporary PC IP = Used while configuring OpenWrt via Ethernet, before bridging.

Important Tips:
-
Choose an OpenWrt LAN IP on a completely different subnet than your main router.
-
Make sure the WWAN IP (for connecting to main Wi-Fi) is outside the main router DHCP range or reserved in the main router settings.
-
The Temporary PC IP is only used during direct Ethernet setup before bridging or switching to DHCP.
