help OpenWrt Build for USB Tethering FAQ
How do I set up USB tethering on an OpenWrt router?
You need to install the necessary USB tethering packages, typically 'kmod-usb-net', 'kmod-usb-net-rndis', and 'kmod-usb-net-cdc-ether', depending on your phone's tethering protocol. After connecting your phone via USB to the router's USB port, enable tethering on the phone and configure a new interface in OpenWrt's network settings pointing to the usb0 device.
Which phones are compatible with OpenWrt USB tethering?
Most Android phones work well with OpenWrt USB tethering using either RNDIS or CDC-Ethernet protocols. iPhones can also work but may require additional drivers and tend to be less reliable due to Apple's proprietary tethering implementation.
Can I use OpenWrt USB tethering on a Raspberry Pi or other SBC?
Yes, OpenWrt can be installed on single-board computers like the Raspberry Pi 4 or various GL.iNet devices, and USB tethering works the same way as on standard routers. You need a build that includes the USB networking kernel modules, which may need to be compiled or installed post-flash.
How fast is internet speed through OpenWrt USB tethering compared to Wi-Fi?
USB tethering typically provides more stable and sometimes faster speeds than a mobile Wi-Fi hotspot because it avoids wireless interference and uses a direct USB data connection. Real-world speeds are usually limited by your cellular connection rather than the USB interface, which can handle well over 400 Mbps.
