C881G-4G-GA-K9 %PLATFORM-4-CELLULAR_MODEM_SKU_MISMATCH

I have got a 881 router with backup connectivity via 4G.

My 4G stopped working and now I am receiving the errors below.

 

*Jun 24 07:15:05.534: %CISCO800-2-MODEM_UP: Cellular0 modem is now UP
*Jun 24 07:15:25.545: %CELLWAN-4-MODEM_COMM_FAIL: Communication between Modem and IOS failed: link recovery resets modem
*Jun 24 07:15:57.145: %PLATFORM-4-CELLULAR_MODEM_SKU_MISMATCH: Mismatch detected between installed modem Unknown modem on SKU type C881G-4G-GA-K9. Expected modem for this SKU is MC7304
%Remove Dialer Profile Configuration first.

 

Can you provide me the software needed to upgrade the cellular modem.

 

Best Regards,

Wendell

action 1.0 cli command "enable"
action 2.0 cli command "reload"
