Daryl,

you are going to need IP plus. it is:

c2600-is-mz.122-8.T5.bin. This also bit be awhile back on an install. Basically any IP plus IOS that has "is" as the identifier.

I've never had to upgrade an IOS

Who do I contact to get this c2600-is-mz.122-8.T5.bin file ???

You need smartnet coverage on the router to get access to CCO to download the software that you are looking for. YOu will need to associate the smartnet contract number with a login name (CCO login) that you can sign up at
