Microcell not working

My iphone 6 will not make or recieve calls with the microcell. If I disconnect from the microcell, I have 1 bar and can make/recieve calls with poor connectivity. My phone says I am connected to the AT&T Microcell network and shows all bars but I can't make/revieve calls. I have deactivated, reactiviated the microcell to no avail. I have deleted/readded the phone numbers and nicknames and it's still not working. I have toggled the airplane mode and turned my phone on and off and that did not help. This is extremely frustrating as I have spent hours trying to make this work. Any ideas?

Re: Microcell not working

Unplugging it is just a power reset. That basically forces the MicroCell to reinitialize itself. That sometimes works. A more complete reinitialization is to do the hard reset, which resets the MicroCell back to default settings and forces it to go thru the Initial Activation process again

(see Guide link in my sig).

 

If your jitter is still the same, fluctuating all over the place, then that is something that you will have to take up with your ISP because there is nothing that AT&T can do about it. The new MicroCell may be able to handle jitter a bit better but ultimately that is a line quality issue which can only be addressed by your ISP.

Re: Microcell not working

I find that I do have to power cycle my Mcell occasionally when I see that its 3G light is flashing.  A quick power cycle and it is running again.  I have no idea how the Mcell lost its connection but it could be that using a wireless range extender to connect my Mcell to my router as I do is contributing to this.  Unfortunately, in order to cover my entire house I have to locate my Mcell in a place that is remote from my router and I don't want to string 100 feet of Ethernet cable to connect by wire.  If I let the Mcell go long enough, it will usually reconnect on its own but I've just grown accustomed to power cycling it when I see the flashing 3G light.

Re: Microcell not working

Hello Community!

 

One of the most common topics we see on the forums is regarding the Microcell.  Specifically, how to identify and understand the differences between the LED light indicators on the device as well as troubleshooting steps to resolve any issues.

 

The information contained below is a combination of the great community content, as well as information provided by our Advanced Technical Support team that supports the Microcell every day.

 

MicroCell LED Guide

 

Power LED

  • Off– No power to MicroCell.
  • Solid Green– Microcell has power.
  • Solid Red– MicroCell is either still powering up or is in an error state. Please unplug the MicroCell from power and plug it back in. If the LED remains red, please try an alternate power outlet or alternate power cable. You can also test the ac adapter with a voltmeter. It should read 16VDC ± 0.5. If not, replace the adapter with one of the exact same power rating.

 

Ethernet LED

  • Off– No Ethernet cable connected. Please make sure both sides of the Ethernet cable are firmly attached. One side should be plugged into the Ethernet port on the MicroCell and one side should be plugged into an Ethernet port on the modem or router. Ethernet cables should click when inserted into an Ethernet port. If the LED does not light when both sides are firmly attached, please try an alternate Ethernet cable. The MicroCell has been tested and works with Ethernet cables up to 15 feet long.
  • Solid Green– The Ethernet cable is connected and the MicroCell has been assigned a valid IP address.
  • Flashing Green– The Ethernet cable is connected but the MicroCell has not been assigned a valid IP address. Please power cycle the modem, then router, then MicroCell in that order. If the Ethernet LED continues to flash, please ensure DHCP is enabled on the modem or router. The MicroCell requires DHCP to work.

 

GPS LED

  • Off– No location check is being performed at this time. The MicroCell is either unplugged or is going through activation.
  • Flashing Green– The MicroCell is performing a location check. It is scanning both for GPS satellites and for local cell sites.
  • Solid Green– The MicroCell has completed the location check.

 

Computer LED (only on white model MicroCells)

  • Off– Nothing is plugged into the computer port.
  • Flashing Green– Traffic is passing through the MicroCell.
  • Solid Green– No traffic is passing through the MicroCell.
  • If continued issues occur, it is recommended to not use the Computer Port because of potential issues with the connected computer’s internet settings.

 

Network or 3G LED

  • Off– The MicroCell is not activated. It is either powered off or going through activation.
  • Flashing Green– The MicroCell is not activated. It is going through activation or is experiencing a connectivity issue. Please wait 90 minutes after registration. If the 3G LED continues to flash after 90 minutes, please review the Firewall &Router settings and make sure the modem or router are appropriately configured for use with a MicroCell.
  • Flashing Red– The MicroCell has failed the location check. Please ensure the MicroCell is registered to the correct address. Please power cycle the MicroCell to trigger a new location check. It may also help to relocate the MicroCell to a location with a clear view of the sky. If the MicroCell fails the second location check, please contact AT&T Customer Care.
  • Solid Green– The MicroCell is fully activated and is broadcasting signal.

 

We also have comprehensive Video content to help you navigate any issues you might be having:

 

Note: A failing AC adapter can affect any of the LED lights so it’s always a good idea to check the adapter with a voltmeter, especially if the MicroCell is a few years old or you have experienced numerous or unexpected power outages.

All of my lights are green. I cannot call anybody and have them hear me. Also my cordless home phone device has a flashing green light. Please help me


Can you be a little more specific on what you have and how it is setup. Your cordless phone has no bearing on the MicroCell so your issue is a bit confusing.


@Outlaw3944 - I had to refer back to my own Tech Guide after I thought a bit more about your cordless phone. I'm assuming you have the AT&T Wireless Home Phone (WHP)? If so, the flashing green light (signal strength indicator) on the phone means it is connected to the MicroCell. If the indicator is a solid green, yellow, or red, that indicates signal strength to the nearest tower.

Re: Microcell not working

For the last 4 days the Microcell is down first thing every morning. Resetting it does not fix the problem as my Microcell is in an internal closed (since 2011). I have to use the connected antenna and place it outside. I have not had to do this for a long time. Usually reset works. What is going on? Have there been updates that have screwed thing up?  For years it has worked fine but this week not so much. Once I place the antenna outside it comes up and stays up all day. Weird that first thing in the morning it is down. Help!

Re: Microcell not working

@bobtempleton - by connected antenna I'm assuming you are using an external antenna connected to the external antenna port? There have been no updates in the last week or so that I am aware of.

 

What does the light pattern on the MicroCell indicate when it is "down"?

 

If your MicroCell is that old I would check the ac adapter with a voltmeter. It should read 16VDC +/- 0.5 with no load. We've seen all kinds of odd things when the adapter begins to fail.  Post back what the voltmeter reading is. I have a blog on the Community Forums page with some basic information.

Re: Microcell not working

Your symptoms would indicate that the Mcell is trying to verify your GPS coordinates at night and since your Mcell is in a closet with no external antenna, the Mcell can't determine its location and drops the connection.  The fact that you can connect your external antenna and the problem goes away seems to validate the problem.

 

The Mcell is suppose to be located in a place that has adequate RF signal access to at least 3-4 GPS satellites in order to determine its location and that location must match the physical location that was entered when the Mcell was registered.  As to why your Mcell is now requiring a more frequent GPS verification than in the past could be due to a recent change in firmware programming.  AT&T doesn't make public firmware changes so it's difficult for us to know what, if anything, has been changed or when it happened.  You may find that you'll have to keep your external antenna connected in order to avoid the nightly disconnects now.

 

Do you have WiFi Calling capable phones?  IMHO, WiFi-C is a better solution for coverage in homes that suffer from poor cell tower coverage than the Mcell provides.  I've used both and I'll never go back to my old Mcell again.

Re: Microcell not working

@bobtempleton - @Avedis53 is probably correct about the GPS check. AT&T will periodically perform a maintenance check late at night and sometimes part of that check is verifying your location. If it can't verify your location via the local tower it will check using the GPS coordinates sent by the MicroCell. If there is no GPS lock, then location can not be established and you will not be able to connect to the AT&T Mobility servers. I'm surprised that this hasn't happened more often. Check the adapter just to rule it out and then connect the external antenna. If the adapter checks out, and you can re-establish connection to AT&T, then it is more than likely a GPS problem and your options are to either keep the external antenna connected, or move the MicroCell so that it is within 18" of a window with an unobstructed view of the sky. Keep in mind that the newest model of the MicroCell (black, DPH-154) does not have an external antenna port anymore so if you decide to upgrade your MicroCell you will need to figure out a better way to set it up.
