openwrt.org › docs › guide-userAug 15, 2021 · Connect to client Wi-Fi network. This page will explain how to connect your OpenWrt device to another Wi-Fi network by using its own radio. Due to technical limitations, your OpenWrt device will create its own subnet (in the example below it's 192.168.2.x while the Wi-Fi router's subnet is 192.168.1.x ) just as it would when connected to a modem, your OpenWrt device and devices connected to it will be able to reach the Internet, but won't see devices connected to the other Wi-Fi/router).
