I have replaced a Wavecom modem at a customer and would like to upgrade the old one to the most recent level of firmware to be able to continue using it in a less demanding environment.

I can’t get in to download the obsolete files - there appears to be nowhere to click.

Can someone please explain the process of upgrade and has anyone got the correct files.

The modem is a Wismo WMOD2 FastTrack M1203A-ON and it still works fine, but gets muddled with the modern network.

Thanks

Dermot
