Cisco IOS Upgrade

I found that i need to install an IOS upgrade to my router to use the HWIC-1FE module I purchased.  I have a Cisco 2821 router. From the spec sheet i read that i need a minimum IOS of 12.4(15)T.   I called my Cisco retailer and he send me the following file c2801-advsecurityk9-mz.124-22.T.bin . When i tried to load this it says it is not for my hardware.  I am guessing this is because it begins with c2801 and i need it to be c2821?  Should i ask for a different file?  Could i just rename it?  Thank you for your help!

I would not suggest changing your file name since I doubt the source of the file. Download the uggested IOS fresh from website and always verify MD5 checksum after copying it


According to cisco software advisor, the ios for your hardware is:
