Troubleshooting

Make sure your device is connected to the OpenWrt router. Try 192.168.1.1 or the router IP address shown in your network settings.
Open Network → Interfaces → LAN → Edit → DHCP Server. DHCP-Options are usually inside the General Setup section.
Reconnect the device to Wi-Fi or restart it. DHCP DNS changes are usually applied after the device renews its network settings.
Check your WAN interface settings and disable using DNS servers advertised by your ISP if needed. Then save, apply, and reconnect your devices.
Make sure your UnGeo account is active, your current IP address is added in the Client Area, and the UnGeo Smart DNS servers were entered correctly.
