I have had a 3g microcell for over a year. Suddenly this week the 3g light starts flashing and phones no longer connect. I have:
deavtivate and reactivated too many times to count
factory reset my modem, router, microcell
replaced microcell with new one
opened all ports listed in various posts and att support site
turned cellular data and 3g data off on iphone
used priority set up (modem then 3gMC then router, this is how I am configured now)
What ever I try, there is still no connection back to att network. ATT support says it must be charter cable and charter cable says it is att. The only port I can not touch is 123 NTP. I don't know what is hooked up to it, but it is not accessible to me. However, using the priority config should bypass any port issues...right?

Thanks for the feedback! We've seen that certain routers do not play well with the Mcell. While it is a somewhat expensive troubleshooting effort to start changing out routers to find one that works, one can usually return the router if they find that it didn't help their situation.
Good luck with your Mcell!

Thanks Avedis and no problem. I agree with you that troubleshooting the expensive way is not always best but yes, we can certainly return items if there's no improvement. That was going to be my plan if this new Linksys router didn't make any difference but man, it sure has! I love this thing! It's getting rave reviews all over the place too.

Were you able to get any information from Charter that you can now pass along? I am in Michigan and my microcell quit working back at the end of May. I am on my 4th replacement and it still won't activate. I've have AT&T check the GPS location (solid green) but every time the 3g light turns blinking red. Hours upon hours have been spent on the phone with AT&T and they have not been able to resolve this issue. I have had charter internet for almost 15 years now and I know they did push through an upgrade earlier this summer. Any information would be greatly appreciated.

Charter has stopped communicating with me. The engineer who was very helpful at the beginning will not respond to my emails or pm's anymore. This seems to be a regional thing because I know of other Charter subscribers who have the MicroCell and are not experiencing any problems. Have you reviewed the Tech Guide and tried all of the troubleshooting steps, just in case?

Unless the OP has changed something in his home network, going through 4 Mcells after one was working previously would suggest that something has changed on the ISP side.
Perhaps a router reset would help but not knowing the home network setup or equipment, that's hard to determine. Would definitely try connecting the Mcell directly to the modem and bypass the rest of the network to see if that helps to establish a Mcell connection.
If that doesn't help, he should send a PM to ATTCustomerCare, describing what he has done so far and his geographical location so AT&T can see if they have had any other problems reported in that area.

Did you ever get your microcell working with Charter after the blinking green 3G light on the microcell? My microcell stopped working today. I've spent three hours on the phone with AT&T and Charter. Each said it is the other's problem. I'm inclined to believe that the problem is Charter because they have blocked the ports that the microcell is required to access the AT&T servers. Charter will not grant access to these ports so my microcell is of little more value than a brick. And I have no phone service. How can Charter do this without any notification? I have verified that the all of thte ports required for microcell access have been BLOCKED. Now what do I do? How can Charter get by with doing this?

I've linked your post in the other thread to the Admins and they will look into it. It would be best to keep your posts to a single post, preferably the other one so we, and others, can easily respond and track.
Charter, like anyother ISP can pretty much do what they want and justify it was a "security measure". Let me see what I can find out before we jump to conclusions. As far as I know Avedis53 still has a perfectly functioning MicroCell.
By any chance did you try a hard reset on the MicroCell?

I woke up also to the same issue. My microcell after over a year just stopped working. Charter is saying it's port 4500 that is blocked. Any help would be greatly appreciated.
I'm located in Louisiana.

Charter seems to be having issues in specific areas because you're the first non-West Coast person to report that Charter is blocking a port (possibly). Unfortunately, if it is Charter that's blocking port 4500 (the most common port blocked) then they will have to correct it because AT&T can't. Did Charter tell you port 4500 was blocked or did you use a port checking app?
I've linked your post to the Admins and they'll look into it but don't expect much, especially if it is Charter's problem. I'm wondering if they are having network switch issues due to weather?

I do know that our area is being upgraded to the new Charter Spectrum or whatever they are calling it. This might be the cause of the new issue.
I spent most of the morning with AT&T going through their tireless check off list when I had already performed those tests and plenty of more. Of course you have to go through them anyway and finally they got a manager on the phone. The manager said from their side it was port 4500 being blocked as they could not access the Microcell either. I will contact Charter and see if they point the finger back at AT&T or just throw their hands up.

A couple weeks ago my AT&T 3G MicroCell connected through Charter quit working. I am located in southern Oregon. I had made no changes that could have caused this. Now the bottom connection is eith or off or flashes continuously. I spent an hour and a half on the phone with an AT&T tech person tyying many different solutions, including connecting the MicroCell directly to my cable modem (thus eliminating router issues), and openin g up the four ports on the router that the MiocroCell uses. None of this has worked. Apparently the Charter-based problems exist here also!
Unfortunately, alternative cellphone companies do not provide better cell coverage in the part of town where I live, so switching carriers is apparently not a solution. Help!

What has happened in the past with Charter is that they have done regional upgrading on their system which has caused connectivity problems with the MicroCell ( a switch configured wrong for example). It's unfortunately not a system-wide problem ( I saw your other post) so it's hard to determine the cause. Unless we start to see similar problems in other Charter areas it's going to be difficult to pin-point. I would send a pm to CustomerCare with the problem, what you have done to correct it, your account information, the best way for them to contact you, and your location. It could just be your MicroCell Service Area but until AT&T gets similar complaints from the same are they will treat it as a localized problem and not prioritize it.
I would also contact Charter to see if they are doing any maintenance/upgrades in your area. Don't be surprised if they can't or won't tell you anything and direct you back to AT&T.
I have a contact in Oregon who also uses the MicroCell with Charter so let me see if he has any issues.

No issues here on the central Oregon coast with Charter.
You can certainly test your Mcell at your brother's house to see if it works, but I suspect your problem is a localized issue with Charter as we've seen this before. Let us know how your test turns out.
