 +==== Installation using web interface ====
 +
 +Cudy provides a version of OpenWrt 21.02.1 that can be downloaded [[https://www.cudytech.com/openwrt_ramips_wr2100_download|here]] and upgraded using Cudy's web interface. After this upgrade you can use the normal OpenWrt methods to change the OpenWrt firmware.
 +
 +===== Returning to OEM firmware =====
 +Returning to the stock Cudy firmware from the OpenWrt installation is possible using TFTP, using  [[https://www.cudytech.com/filedownload/282847|this]] image. TFTP server should be configured with 192.168.1.88 as IP address.
 +
 +  - Press the "Reset" button and hold it. Before the Cudy router is powered on and before TFTP start to download the firmware, don't release the "Reset" button. 
 +  - Power on the Cudy router. 
 +  - You can release the reset button only when the status LED flashes red and blue quickly, or when TFTP starts downloading firmware.
