Which Case ID you are refering ? Are you Looking for the Serial number of your Router ? To locate the Serail Number of your Router, Flip your router upside down and below the Linksys logo you will find the Serail Number of the Router.
To find out your Case ID or the Reference number you need to call Linksys tech support, I think you will find that information with them.
