My Resmid10 also suddenly stopped sending reports to MyAir. I was told problem was 3G card with carriers switching to 5G service. Received new machine under warranty because of heating element failure. Data was still not transferring, but performed a software update after receiving the new machine and data started transferring to MYAir. I was told by the vender that the modem was not changed in the new machine but, whatever the reason, my data is not transferring.
