The 3G MicroCell was designed to automatically confirm that it has the latest software version each time you power up so I don't think this would be a software update issue. 

I've responded to your PM, please take a look when you get a chance. 

I had this problem for awhile last winter and fixed it following someone's suggestion. Now it has started again. I wish I could find the post that helped me before. There was a particular sequence to follow of unplugging and plugging and unplugging again etc, etc.

Interesting info! Let me know if this works for you. We can mark it as an accepted solution if it does.

It worked...no red flashing light this morning. Solid green!

Great news and thanks for sharing your steps. I really appreciate it!

Just so you know Ms. Community Manager, this solution only works for about a day, then its back to flashing red.  Do you actually have a permanent solution that you know of?  Or are people with this problem just basically screwed?

Not true that it only works for a day. It has worked for months at a time for me. 

I had the same problem (http://forums.att.com/t5/3G-MicroCell/MicroCell-fix-kind-of-for-me-anyway/td-p/3339907) even though the GPS light is solid, i believe that IS the problem here........$6.00 for an external antenna, at the very least it will cut the reboot time, mine went from a 1 hour reboot to under 2 minutes......and before the external antenna i had the flashing lights EVERY morning and EVERY evening......not one time since.......6 bucks, try one,.......oh, and i did ALL that other stuff, the "unplug sequence" , the port forward, and a new microcell......none worked, antenna did.....that is all.....

What kind of antenna and where did you get it.

25 foot cord allowed me to run it through the floor to a second story window and i duct taped it in there......

I'm sorry you're still having problems. This solution has helped quite a few folks, but looks like it didn't work for you.

Im not so sure ATTCustomerCare WILL help you out......i spent HOURS on the phone with them on MANY differant calls (all of them VERY nice) and even asked them about the antenna port on the back and why is it there and why did no antenna come with it and i was ASSURED that wasnt the problem.....even now, after i IGNORED them and fixed it myself , i call them back to tell them of this and they seem to not believe it or doubt me somehow........(my guess is they dont want to have to buy antennas for people but that would seem cheeper to me than all the phone time they spend on trying to fix them).........that being said, I LOVE THE MICROCELL!.....we have ZERO signal here without one and our phones would be useless......

I didnt mean that they wouldnt try to help you, they have been very friendly when i called (several times) but for some reason they are not aware of, or can not speak of the antenna port.....one even told me it didnt have one or it wasnt "functional"......imo, this should be the FIRST thing that is tried when there is a problem (even IF the GPS says it is locked as mine did but really wasnt).......
