My MicroCell operated flawlessly for 2 years. Now, it will lose connectivity every 1 or 2 hours. First the 3G and GPS lights will go out. Shortly after, it will stop communicating with the Ethernet connection to the router and that light will go out. Powering it off and on resolves the issue, but only for a few hours, when it will happen again. Any explanations?

Thanks for your response.
Yes, the power light is a solid green. The AC adapter feels quite hot, but that is the only thing I've noticed related to power.

I had to go up and feel my AC adapter after reading this, since my Mcell is working properly. It is above room temperature but couldn't be more than 90 - 100 degrees F based on my uncalibrated fingers. If the AC adapter actually feels "hot" then it might be faulty.
If you have a multimeter, unplug the AC adapter from the Mcell and test the voltage output at the plug. Touch the positive probe to the center of the plug tip and the negative probe to the barrel of the plug and see what your DC voltage is. I just did that with mine and it reads 15.98 VDC. One would think that it should read 12 VDC but it reads higher because the adapter is unloaded when you test it. While I can't measure the voltage while it is plugged in, I'm sure it is running 12 - 13 VDC while driving the Mcell.
I would say if your AC adapter output voltage varies significantly on either side of 16 VDC, then you may want to replace your AC adapter and see if that helps your situation.
If it measures 16 VDC, then I'd suspect that your Mcell has borked and you should talk to AT&T about a replacement. Since yours is off warranty, don't expect a free replacement but with some discussion, you may be able to get them to sell you another one at a reduced rate.

Thanks Otto for your help. I purchased a replacement power supply, and I'm working at 100% once again. I would not have thought that the power supply would be responsible for erratic connectivity. In addition, the new power supply is just warm to the touch. A hot power supply is definitely a sign of trouble.

I'm glad it worked out. The MicroCell does seem to be a bit particular about the power it receives so it doesn't take much for it to start getting squirrely and dropping the connection.
