I think I should learn the key facts how to find and identify to go through any IOS upgrade process and here I am stuck again and unsure which one can be added on.......

We need to upgrade this 3640 to its latelst bugg free IOS I possibly can.

Questions:

1) Which would be the latest stable IOS which can be installed on this router

2) Upgrading the flash would that enable us to upgrade it to any better IOS ? the custoemr is open for suggestions hardware and software

They hvae two 3640 routers onsite.

IF anyone can advise, any help will be greatly appreciated.

Re: upgrade IOS on a 3640 !

yes I do have access to that link.

I always would get confused with the steps

1)

2)

3)

4)

which would make me beleive that is the right IOS for this device or a specific device for e..g this 3640

cheers

Re: upgrade IOS on a 3640 !

I will surely rate the post but can you kindly explain a little how you confidentaly reached that conclusion ?

for e.g.

how can you confirm that this IOS can be installed on this router i.e. will it fit in the flash and is there enough memory for it.

I have managed to get the show ver of this rotuer but I need to understnad some basics so i can do this on my own in future.

The image file you have suggested earlier I am guessing this will not require any hardware upgrades correct ?

cheers
