Re: HWIC-3G-GSM not restart connection

Hi peraocompany !

Have the same problem here; I use the same configuration with a CISCO1921 on IOS 15.3(2)T. Everything works fine until I touch the interface with "shut - no shut" - the profile stays INACTIVE after that.

You updated the HWIC-3G-GSM with a new firmware ? My data here:

Modem Firmware Version = H1_0_0_7MCAP G:/WS/F

Modem Firmware built = 10/26/06

Hardware Version = 1.0

Where did you get the firmware ? Can't find a valid link in the Cisco Download Center ?!? ...
