Hello,
This is a known issue with a certain model of internal modems. It is not related to the CPU usage or operation of the device. There were a few reports regarding this issue:

I rolled back fw to 07.05.4 and then it’s working perfect again.
I have updated with keep settings off every time.
Seems to be something wrong in the new fw, or is it something else?
Our and modem manufacturer RnD teams are working on this issue and hopefully we will have a solution soon.
Best regards,
