Hi,
I changed 4G module with new one. The new one EHWIC-4G-LTE has SIERRA MC7710 and don't work. The old one has SIERRA MC7304 wireless. I'm using it with Cisco 2951 router, IOS c2951-universalk9-mz.SPA.157-3.M8. I try to install 4G module firmware - MC7700_03.05.29.03_00_generic_000.000_001.cwe from cisco page. After i upgrade firmware (Cisco 4G LTE Software Configuration Guide - Cisco) in router i get message that 4G module is on hold, and please upgrade firmware, but there isn't anything in documentation associated with that router message. In documentation i find that MC7700 series firmware is supported with Cisco IOS 16.5.1 or Later. Can someone tell me if this is why the module is not working?
