@hansm0leman have you done a modem restart/reboot? Give that a go. Unplug the modem from the wall socket, wait for 10 to 15 seconds and plug it back in. The modem reboot should run the firmware check to determine if the modem is up to date or not. If not, it should update automatically. Although there is a modem reboot built into the update process, I've always found that a factory reset after a production version update, or at the very least another modem restart should ensure that the modem behaves as it should.
If that still does not work, call tech support to have the modem added to the update list, which should result in a firmware update overnight.
