EAP-TLS/TTLS Network Certificate renewal causes wireless i-STAT analyzers to lose connectivity

Our facility updated the network certificates since they were about to expire. As a result, all i-STAT analyzers lost connectivity to the wireless network. Unlike other wireless devices, the i-STAT analyzers do not automatically accept the new certificates. According to Abbott Tech Support, each i-STAT analyzer needs to be configured again using the instructions in bulletin 726066-00I. The statement in Appendix 3 says, “The timestamp generated at the time of Wireless Module configuration is the PC system clock date and time. Therefore, the Wireless Module must be configured using the i-STAT 1 Wireless Setup Utility at a date and time within the start date and expiration date of the certificates.” It is industry standard now for these certificates to only last 1 year. I'm dreading having to re-configure each i-STAT every year from now on. Has anyone found a way around this?

Who initiates the Certificate Validation renewal, Abbott or the client?  Also, does this only apply to the three encryption's listed above. 

Your IT department will renew the certificates all on their own. They will probably not know or think that they need to notify you. I do not know if there is an alternate encryption that can be used on the wireless i-STAT analyzers. Our analyzers are set up with WPA2 and PEAPv0 / EAP-MS CHAPv2 and all had to be reconfigured in order for them to connect again to the network.
