New ATT MicroCell arrived today:( HELP

I have had the existing 3g MicroCell for years and it was great.  However, as soon as I plugged in the new grey ATT 4G device (Nokia) that arrived in the mail today, it will not connect!  I see some other posts with the same issue. ONLY A BLINKING WHITE POWER BUTTON and BLINKING ORANGE INTERNET BUTTON.  I have plugged the device into both the wifi and router, rebooted many times, nothing.

Arris Surfrider Modem, Google Mesh wifi (all worked before).

Any thoughts would be much appreciated. No cell service now.

@cifox70 Power cycle your system (router, modem, or gateway, and Cell Booster). If that does't work, Reset the Cell Booster by holding in the Reset button for 10 seconds.

My new Nokia has all white lights EXCEPT the 4G LTE light. Any ideas?

@Pwhack How do you have it setup? Have you power cycled the Cell Booster as well as the router, modem, or gateway? Are you in a service area that is ready for the Cell Booster?

Same thing happened to me. Had Comcast come out who said the problem was with AT&T. Customer Service rep told me to register device and wait 48 hours for tech to check network. If this is a known issue, AT&T should be telling customers so they don’t waste hours troubleshooting something that is not fixable!

@HoneyBunny20 I have Comcast as well and they have absolutely nothing to do with the Cell Booster, nor will they help you troubleshoot it. It's not their product. In fact, that's true for any ISP.

AT&T has had some serious issues with a lot of the new Cell Boosters. The 48 hours is just a stalling technique because the Engineers are still trying to get the backup configured and running smoothly for everyone. Some folks had zero issues (I was up and running from unboxing to full service in 70 minutes) and others are in the same situation as you are in now.

How do you have it setup and what is the issue? It's hard for me to keep track of all of the issues for everyone that I am replying with.

Registered and registered several times. Just the top 2 lights are blinking and no connection to the internet. Called AT&T yesterday and they trouble shooted with us for about an hour with no resolution. They told us it was related to our internet provider, possibly a firewall issue preventing Comcast from seeing the device. Was able to get a Comcast tech out to my house yesterday afternoon, he tried and even consulted another tech. He showed us that all our other devices could be seen (security cameras, etc.) but not the cell booster. He referred us back to AT&T who tried to make us walk through everything the previous AT&T rep did and then told us to wait 48 hours for the AT&T tech to check our network. 

Seems like many people are experiencing this same issue. AT&T should at least alert their customer service reps so they don't waste their and customer's time trying to connect this device.

@HoneyBunny20 It's not a Comcast issue. I was up and running from unboxing to full use in 70 minutes with Comcast.

Comcast will not be able to help you with this because it is not their product and will just point you back to AT&T, which they should do. That being said, I use my own modem and router and not the Comcrap-supplied equipment. You should at least see the MAC address of the Cell Booster in the router's DHCP table in you know how to access that.

How is your Cell Booster setup? The flashing power light usually indicates a failed download so it might be a good idea to either Reset by holding in the Reset button for 5-10 seconds or a full factory Reset by holding in the Reset button for 20-30 seconds. The connection between the Cell Booster to your router needs to be established first before any further troubleshooting can be done.

We relocated it to another spot in the house and it now it up and running. Who knows if AT&T did something on the network to make it possible or not but glad it's resolved.

@HoneyBunny20 That is very common. Quite often you need to find the sweet spot in the home where the Cell Booster signal is the strongest because of orientation to the cell tower, where the cell tower signal is stronger than the Cell Booster and the phone has a hard time locking on to one signal. The Cell Booster does not need the local tower for making/receiving calls but there can be "competition" for the signal that the phone connects to. This is all explained in my Tech Guide which should be available in my sig line later on today.

I had no progress with connecting until I open port forwarding on my router. I realized I needed to do this because of this forum. I tried to avoid it, but with youtube it wasn't to bad. Post responding to jjknight was right "ensure ports UDP 500, UDP 4500 and UDP 123 are opened " to prevent the firewall from blocking communication with the network, as this is connected with the flashing white power button and flashing internet orange button concern"
