My GPS, Ethernet, and power light are on with a solid green. My 3G light is a solid red that flashes every three seconds. I use a Netgear router/modem; honestly, I'm not sure what a modem or router looks like but I plugged the microcell's ethernet into the Netgear. I've tried disconnecting then reactivating the microcell. No luck.
Any advice on how to troubleshoot this issue would be awesome. I live in the countryside where cell phone reception is severely limited. Thanks!

Thank you!!!! This just worked for me on 12/8/16. I troubleshooted on the phone with ATT yesterday and they could not get it to re-activate. They said they would need to send me a NEW Microcell which they have done. I tried your fix this morning and it worked like a charm. Now I have another new Microcell on its way to my house. How come ATT does not know about this fix. Crazy!?

@kalrakshay - it would be helpful to us to know what exactly fixed the flashing red 3G light. Typically a flashing red 3G light indicates location verification failure.

@kalrakshay - I'm surprised that worked but I'm glad that it did in your case. We recommend either a complete power cycle of your system (router/modem/gateway first and then the MicroCell) with no unplugging of cables. The exception being the power cable for the MicroCell. If that doesn't work, then a hard reset (instructions are given in my Tech Guide).

The cable unplugging, power cycling should work , Do exactly its mentioned..
1) With the microcell flashing red, unplug the ethernet cable while leaving power plugged in.
2) Wait 2 mnutes, unplug power cable.(whileethernet is unplugged).
3) Wait 30 seconds, plug power cable in with ethernet cable unplugged.
4) Wait 2 minutes, plug in ethernet cable. (while microcell is powered on)
5) Wait 2 minutes, unplug power cable (leaving ethernet plugged in).
6) Wait 30 seconds, plug in power cable. (with ethernet cable plugged in).
This should clear the red 3g light. If it does not, try power cycling again (unplug power, wait 30 seconds and plug back in).

Interesting fix for a location error. It would be nice to see how this holds up once maintenance is done by AT&T, part of which is verifying the location either by sent GPS coordinates or tower location. Glad it worked.

This process, as originally posted by overclockedpc, works, thanks. It is not a permanent solution but it seems to keep the microcell alive for a couple of weeks or more at a time. The good news is that after doing this, at least in my case, the microcell is back and working within a few minutes of completing the sequence.
I agree with many others who have posted that clearly the design of this microcell is very poor, as these kind of problems should never occur and, if on occasion there are glitches, they should be auto-corrected.
Given the design of this Cisco produced Microcell and how it interacts with the AT&T network, it seems there are no permanent solutions.
Also don't waste your time calling AT&T unless you have really concluded your unit is dead and needs replaced.
A better solution for bad coverage areas, e.g. in homes of offices, is cellular over WiFi if your account and device supports this service. (It is not supported by AT&T's GoPhone accounts.)

@pjmacl - there are few"fixes" we have seen over the years that do work on a temporary basis, some of which just don't make sense but they do seem to work for awhile. Correcting the root cause is what we try to do here.

@hughchung - the flashing red 3G light means that your location could not be verified. This can happen after a nightly maintenance check. Re-entering your address sort of resets your location, but if you live in a rural area or similar area, the location check will probably fail again because the received GPS coordinates do not match what is in the locational database.
Sales of the MicroCell has been discontinued as of the end of 2017. The service itself will also eventually be discontinued as well so you need to look into your options, which are WiFi-C (WiFi Calling), if your phone is capable, purchase a cellular booster (see my Cellular Booster Guide, link is in my sig line), switch carriers, or possibly try Google Voice.
