I have had a Microcell for about a year and have had no problems with it other than the occasional failure to do anything on the first call out. Suddenly I have a flashing 3G light and have rebooted and reinstalled it according to instructions that came with the unit. I can think of no issues or occurrences that have happened that might have caused this. Any help would be greatly appreciated. The Microcell is the ONLY way I can use my iPhone 4s at home.
Thanks. Jerry H

I finally spoke with ATT help and the usual fixes did not work. Now the the tech people are going at the problem from their side and are optimistic that a resolution is near. From what you say, this would be the best route for you to take as well. I have done everything that can be done from my side. It is now in their hands from their side. I wish I had more immediate good news gut that is as good as it gets now.
Good luck. Give them a call.

I noticed my microcell was also blinking the 3G (bottom) light yesterday after working fine for almost a year. I, too, have done everything including moving the unit to a different ISP in the same building, de-registering and re-registering, all to no avail. AT&T is sending me a new unit.
BTW, I'm in CT.

The flashing red light is usually attributed to either the unit has failed or an update was applied and the unit failed to reset properly so it thinks it is broken. Apparently AT&T/Cisco has been updating various regions around the country for the new 4G iPhones that were just introduced (educated guess on my part) and the update didn't go well. You can try the hard reset on the back of the unit (little hole on the back labeled reset) and see if that wakes up the unit. It that doesn't work, you'll have to call support

I've had no luck here in Boston. I get no signal without the device. I've struggled with AT&T with little or no service for 9 months since moving here from Indiana. It is likely time to stop giving AT&T my money and break the contract. Why pay for no service in a major metropolitan area?

My 3G light is blinking green, not red. I tried the reset button as well. We'll see if the replacement unit works. I suspect a failed update and AT&T said they pushed an update about a week ago. It could be that my microcell has not ben working for that time since I was away, etc.

So mine is flashing red but working perfectly. I'm not sure I should mess with it. Thoughts??? By the way, the unit is in New Hampshire.
If it ain't broke, don't fix it! It it stops working, try a power reset first.

Troubleshooting Steps offered to me by AT&T SUBJECT: AT&T 3G MicroCell Firewall and Router Settings for Advanced Installations SYMPTOM: AT&T 3G MicroCell is unable to communicate with the AT&T data network. FIX:
This is outlined in the MicroCell Troubleshooting Guide link that I posted. There are also port forwarding instructions for some router models as well as Apple Extreme Base Station instructions.

Mine stopped working overnight, I'm swapping it out tomorrow. I do have a question though, does the unit need to remain near a window after the initial activation?
Some have had luck moving it after activation but I wouldn't. The MicroCell resets after an update (which can happen at any time without advance notice) and will need to be by a window for GPS lock. No lock, no luck. And it's just one more thing to deal with if the update doesn't go well. You could get an extension antenna for GPS. Those seem to work well.

My replacement Microcell arrived and I installed it today. It activated well and works fine. The previous one had failed last week with a flashing green 3G symbol and NO amount of re-booting, re-activating, pressing the reset button could fix it. I suspect it had a failed pushed update as others have surmised as well.
