My MC7700 suddenly stopped working. This is the second time it happened. The first time it happened I purchased a new MC7700 module and all was well again for a month. But now I have the same symptom again so I think it may not be a hardware defect. I have an active AT&T LTE data-only sim in my laptop. Normally the aircard watcher initializes and when the button turns green I can connect. Now it stays red and says “searching”. Hovering over the notification area icon I see “-60 dBm” so clearly it is seeing radio signals. The bars in the watcher are lit but they are red. What does that mean? I captured diagnostics. It is too big for an attachment.
Please look at the GSTATUS output in my previous post as well as the captured diagnostics from my first post if you have a moment, so I know whether the module is defective or not. Could it be that the receiver still works but the transmitter died?
I had not made any configuration changes at all just before it started being unable to connect.
How susceptible are the MC7700 modules to overheating (see above: 54 Celsius) ? My notebook originally had an MC7710 from the factory and now I have an MC7700 in it to use with AT&T LTE. I used foam pads on both sides of the module because that is how the mc7710 was installed. Would it be better to leave the module exposed to moving air (seems located close to the fan), instead of using the foam pads originally there? Also will use of the GPS contribute significantly to heat?
