I figured it was worth posting here so I have yet to have success with anything else.
I live in an area almost exactly inbetween three AT&T cell phone towers, so subsequently my phone is constantly switching singnals from one tower to the other giving me very inconsistent service. After diagnosing the problem with AT&T about six months ago they sent me a micro cell free of charge, and it worked absolutely fantastic until....
About a week ago my microcell's 3g light started flashing, this had happened once or twice before so I performed a simple reset but it did not fix the problem like before.
and none of these fixed the problems.
My current internet is about 30mbps DL and 10mbps upload so that isn't the problem
The ports on my router are all opened, and nothing has changed to effect that
After going extensively through the forums I am kind of at a loss of what to try next. Any suggestions from people on the forums?
I am currently located in the East Bay of California (Alameda, CA)
Thanks very much.

So you're saying that you had land-based internet before satellite and you were still losing signal at around 2am? Interesting. I found my original User Manual for the DPH-151 model. On page 18 it says, " You need high speed internet service over DSL or Cable (satellite internet service will not work)." This particular unit was purchased in 2010 and still works fine (even though it's been retired and replaced with the new, DPH-154 model).

Glad to know I'm not alone. Started just about a week ago and suddenly I get all the lights except the flashing 3G light. will contact the tech rep in the forum, but would be good if they communicated with customers as soon as they realized there is a wide spread problem. It's been working perfect the 2 years I've had it until a week ago.

There is no widespread problem that I am aware of. Is your 3G light flashing green or red? Give us more details and we'll see what the problem may be.

I'm in the same boat. My microcell has been rock solid for years. Last week, the 3G signal bars started flashing green. I've reset the thing several times with no luck 😞

Flashing green 3G means you have lost connectivity to the AT&T Mobility Servers. Have you, or your ISP, updated any firmware, hardware, etc , and who is your ISP?

Answer ALL the questions the best you can and then we will have a better chance of helping you.
MicroCell™ TroubleShooting Questions:
1. Have you read the Tech Guide first? 1. 3G MicroCell Technical Guide by Otto Pylot
2. Do you have an active postpaid AT&T mobile account?
3. Is your MicroCell white or black?
4. Who is your ISP and is your service ADSL, cable, wireless or satellite?
5. What are your suscribed download and upload speeds as stated by your ISP?
6. Have you tested your internet speeds (http://www.speedtest.net/)? Please run the test and post your latency, download and upload speeds.
7. Have you tested your connection for VoIP quality (http://www.voipqualitytest.com/)? Please run the test and post the results that are listed under the "Advanced" tab.
8. Are you using the basic connection (modem -> router -> MicroCell) or the alternate connection (modem -> MicroCell -> router/computer)? The alternate connection is not possible with the black (DPH-154) MicroCell as it has no Ethernet output but it can be connected directly to the modem to temporarily test the Microcell without the network connected.
9. Are all of the cables firmly in place?
10. Do you have a combined modem/router (gateway) or a separate modem and router? What are the makes and model numbers for your equipment?
11. Have you met the minimum requirements for router settings as outlined in the Tech Guide?
12. What other equipment (access points, switches, computers, WiFi components, gaming consoles, etc.) do you have connected to your network?
13. What does the light pattern look like on the MicroCell (power, ethernet, GPS, and 3G)? Are they all a solid green or is any of them blinking green or red, and if so, which one?
14. Have you done a hard reset of the MicroCell? See the Tech Guide for instructions.
15. Have you deactivated and reactivated your Mcell using AT&T's MicroCell website?
16. Does the ac adapter feel warmer than the top of the MicroCell where the vents are?

Same thing happened to me.
I was able to solve it by placing the MicroCell further away from the Wi-Fi modem.
It turns out that Wi-Fi interferes with the MicroCell and it need to be at least 2' from a Wi-Fi source. I found this information in the following technical guide -

That information is also in the official setup instructions from AT&T for the MicroCell. Even though WiFi and 3G are entirely different frequency bands, if the unit is too close to the WiFi source there may be interference. However, sometimes moving the MicroCell's physical location orients the antenna such that a more stable connection is achieved depending on building materials, etc.

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
Computer LED (only on white model MicroCells)
Network or 3G LED
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.

My name is Carol
I was wondering if this issue was ever resolved? I recently switched to ATT from verizon, but found I typically had very low signal, so I installed a 3g Microcell. When it works, it is awesome, but it never works for more than 24 hours.
I have deactivated, reactivated, unplugged, reset, replaced, all to no avail. Talked to many technical support folks too.
I'm beginning to think it will never work and should give up trying.
Any help would be appreciated,

We've seen lots of issues with the Arris modems, especially the ones that come configured for TWC. We try to resolve the issues without having the user swap out and/or purchase new hardware. Most of the time we can but if the problem can't be resolved with the questions above, then trying another router/modem/gateway is the next step. Thanks for the post.
