MicroCell Service Area Outages:
The causes for this are many and varied and are beyond the scope of this document
so I won’t go into that here. An outage can be localized or regional depending on the
cause and can be fixed quickly or go on for a week or more. More serious outages
can have a cascading affect and reach across different MicroCell Service Areas over a
period of time. Support is usually the last to know about the outages so when you
experience a sudden loss of connectivity for no apparent reason, and can’t correct it
with any of the troubleshooting procedures found here, it’s best to PM
CustomerCare with your issue, what you have done to correct it, your account
information, and most importantly, your location. Individual connectivity loss can
happen at any time, but if Support starts to see a pattern with the same issues
reported from different locations, the Network Engineers should be notified and
with the location info, it may help them to isolate and correct the problem quicker.
The outage may also affect other services such as the myATT account page so that
attempting to deactivate/reactivate your account, or modify your account in any
way may not work.
Once the outage is isolated and corrected, not all MicroCell Service Areas will come
back online at the same time because it will take time for the fix to propagate thru
the system, and there may still be localized areas that will take a little more work to
identify and correct. You may have to perform a Complete Reset/Activation for
your MicroCell if simple power cycling or any of the other procedures listed under
Blinking Green 3G Light do not work.
Blinking Red 3G Light:
This may indicate a hardware failure but more times than not, it is related to an
update that AT&T pushed, and for some reason when the MicroCell re-booted
something got hung up and the unit thinks there is a hardware failure. Power
cycling the MicroCell can clear the ROM. If that doesn’t work, a hard reset may be
necessary. There is a small reset hole on the back of the MicroCell towards the top.
Power off the MicroCell. Use a paperclip and push the button in and hold for 30
seconds while the MicroCell is powered on. The MicroCell will go thru the re-
start/activation process and that should clear what ever got hung up initially. The
initialization process may take longer than you expect for the reasons mentioned
under the Initial Activation section because of the update. Updates are not always
system-wide and may be regional. You still may be able to use the MicroCell with the
3G light blinking red but it is telling you that a problem is present.
