RUT routers are being constantly improved and sometimes new features are added to the their software. The Firmware image files do not contain the Bootloader program. For this reason, new Firmware doesn't always work with the old Bootloader. This problem can be solved by upgrading the Bootloader to a newer version. This chapter is a guide on how to do that on RUT2xx routers.

Now you can enter the Bootloader menu. Open your web browser and enter your router's IP address into the URl field and add '''/uboot.html''' at the end ('''192.168.1.1/uboot.html'''). This may not work if have connected to the router's WebUI at least once before, since the URL's path may be cached. To solve this problem you can clear the browser's cache or, more simply, open the browser in a mode that doesn't cache browsing information. On '''Google Chrome''' it's called '''Incognito''' and can be reached by pressing '''ctrl+shift+n'''; on '''Mozilla Firefox''' it's called '''Private Browsing''' and can be reached by pressing '''ctrl+shift+p'''; on '''Microsoft Edge''' and '''Internet Explorer''' it's '''InPrivate''', can be reached by pressing '''ctrl+shift+p'''.
