The bin file seems like its supposed to work with another program.
Found this pdf that wil help you. Turns out there is an option on the program to update the firmware which uses bin files:
Go down to page 44. This is the firmware part.
It tells you how to use the bin file using the Wireless ADSL Modem Router Setup Utility, which is set up just like a webpage which you should have got on a cd or is accessible straight from something already loaded into the router.
Read that anyway which should lead you to it
That will definetly help you anyways, or at least I hope it does
