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
