I have a client with some older Cisco hardware and the certificates stored in their 3600 series APs have recently expired. I'm bypassing the authentication on that front for now so that the network stays up, but I'm looking for a better long-term solution that hopefully doesn't involve purchasing new hardware. I saw on another forum that upgrading the firmware can force the certificates to renew, but I've had very little luck figuring out how to do that. All I can find as far as a manual goes for these APs is a "getting started guide" that doesn't really include any info on managing these devices once they're deployed. Any help you can offer would be appreciated.
