there should be no correlation whatsoever between your looking at the SD card and the cellmodem activity.
With the A10 plugged in and blower off; go into My Options, scroll down and select About, scroll down to Internal Modem.
Signal -69dBm (shows 5 bars on signal bars)
Yours might show ---dBm (no signal)
The better the signal the more positive the dBm number; -30 is better than -60
Things to try:
1.) check Signal level on AirCurve to get a baseline for your location.
2.) swap power supplies to rule out that failure possibility.
3.) just for testing: move AirSense to another location and note Signal level.
4.) enable and disable Airplane mode and re-power unit just for grins. My unit sometimes takes a while to find a decent tower.
Not much help, but something to try.

I have it unplugged again and am going to leave it for a while. I'll try this all later or in the morning though.

I had that happen. Cell modem failed on it. Enjoyed the fact the no one (DME specifically) could grab my data. But when the insurance came looking for compliance info, I had to have my machine replaced. Now, that I own my machine, I can airplane mode it. Though tempted to open up the case and pull the connector.

I wanted to learn Binary so I enrolled in Binary 101. I seemed to have missed the first four courses.
