Hi, could someone give enlightenment regarding IOS upgrade for C881-K9. I am looking at the Cisco website and I can see that there are IOS available for download however I am not entirely sure what to download or use from the images that I have found below(attachment). What are the deciding factors/info that I need to check to identify the suitable IOS for the upgrade.
This is what I currently have on the router;
