Hi everyone

If you see 'Error 608 Mobile connection not possible' when using either the K3765 or K4505 USB modem, the below steps will help you to resolve the issue:

1) Ensure Network Connection relating to the device is enabled.

  • Control Panel
  • Network Connections (Network and Sharing Centre -> Manage Network Connections on Vista) or (Start Menu -> type 'view network connections' in search field and double click returned result on Windows 7)
  • Ensure the Lan or High Speed connection using the Vodafone Mobile Broadband Network Adapter (Huawei) is enabled.


2) Ensure Network Adapter relating to the device is enabled:

  • Control Panel
  • System
  • Hardware Tab
  • Device Manager (Control Panel - System Device Manager in left hand menu on Vista and Windows 7)
  • Expand the Network Adapters heading and ensure the Vodafone Mobile Broadband Network Adapter (Huawei) is enabled.


3)
If on VMC 9.4.4 update to 9.4.6 (or higher) available here.


4) If using the K3765, please ensure the latest version of firmware (11.126.03.09.00) is in use. If not please update as follows, ensuring the following before running the firmware updater:

  • Laptop is on mains power
  • VMC software is not running
  • Sim card is removed from the USB Modem
  • USB Modem is not removed from the machine while updater is running
  • Download (from here) and extract the Firmware update utility.
  • Double click to run and follow on screen prompts to apply.


5) Further to this, if using the K4505 and you have firmware 11.818, it is recommended to update to 11.828. This will not resolve the 608 issue, but will improve connection stability especially under 2G conditions. The firmware for the K4505 can be updated as follows:

  • Download the firmware update utility from here
  • Ensure the Sim is removed from the modem, modem plugged in, Vodafone Mobile Connect software not running and computer on mains power
  • Double click the K4505 Update 11.828.03.00.11.B427.exe to run
  • Follow on screen prompts to apply the firmware update ensuring device is not removed and computer is not switched off during the process
  • Once complete, reboot the computer
  • Retest the issue.


If you have any further issues after this, please create a new thread to let us know.

Thanks
