use wifi router as extender

Hi,
I have a iptime N104-r3 version of router from Korea. I want to use this router as extender with my existing router.
Also, is it poissible to change the OS /firmware language from Korean (current version) to English so as I can use it outside Korea.
Thank you for your help and time, I look foward to hearing from you soon.
Regards,
Amit
