Mcell requires power cycle every day to regain connection to iPhones
While I didn't encounter this problem initially when I started up my Mcell a few months ago, it has now become a daily ritual that I hope someone here can help me with.
My setup:
Motorola SB 6120 modem -> Netgear WNR3500L router -> Mcell
The Mcell is connected to the router with a pair of Netgear Powerline 200 Nano Adapters because my modem and router are located in the basement with no exposure to window for the Mcell to see a GPS satellite. The connection is good.
My Charter ISP connection is 30 mbps down and 4 mbps and is rock solid.
What's happening and what I've done so far:
Usually once a day I will no longer see the AT&T Mcell indication at the top of my iPhone 5. When I check my wife's iPhone 4S she has also lost the AT&T Mcell indication.
Turning the phones off and then on does not bring back the Mcell connection. Switching Airplane Mode off and then on does not bring back the Mcell connection.
The Mcell has all solid green lights when I go to check it after seeing the lost connection. If I power cycle the Mcell, the phones will then show an Mcell connection again until the next time they lose the connection which is usually once/day but not at any particular time.
I have the latest firmware on all devices.
When I check my router's admin page after a lost connection, the router indicates that the Mcell's IP address has not changed and it remains the same after power cycling the Mcell.
On the WAN page for my router, I have set the MTU size to 1492 and set the NAT Filtering to "Open" instead of "Secured". No improvement after doing so.
Suspicious of the Powerline Adapters, I tried disconnecting and reconnecting the Ethernet cable from the Mcell to the Powerline Adapter to mimic a temporary loss of connection to the router to see if that affected the Mcell connection. The Mcell connection was not lost.
I have not set any open ports or a static IP address for the Mcell yet. Is what I'm experiencing indicative of this solution? Does anyone have any other thoughts as to what try next?
I don't want to waste my time with an AT&T Level 1 tech support person because their suggestions are almost always worthless. I have better luck contacting user forums and that is why I'm posting here.
Thank God I was able to convince AT&T to give me a Mcell for free because if I paid $200 for it, I'd be very upset right now.
Thanks In Advance!

Just thought I'd post an update of my status. I've still had no reoccurrance of a dropped connection that requires a power cycling of my Mcell since I replaced it with another one provided by AT&T. Today however, I was on my iPhone for about an hour and the call dropped. I saw that the Mcell indicator on my iPhone was gone. Went upstairs to check the Mcell and all lights were solid green. I switched Airplane Mode on and off and the connection re-established itself.
So whatever happened was caused by something else other than what I previously experienced since switching Airplane Mode had no effect on re-establishing my connection with the old Mcell.
I've never had a accelerated battery drain issue as described above on any of my iPhones.

Sounds like the MicroCell has issues similar to connecting to a tower. We just came back from a trip to Arizona and our phone worked fine, most of the time. But every now and then it would lose connection to a tower and get stuck in "Searching". It could be the same thing with the MicroCell. Interference, what ever, causes the MicroCell to start "Searching" and it just doesn't have the ability to correct itself without a reboot.
And yes, battery drain doesn't seem to be an issue with us as well. I'm beginning to wonder if it doesn't have something to do with how AT&T is allowed to adjust it's tower strength for various regions which would result in the MicroCell spending more time communicating between the phone and the MicroCell which would result in battery drain. Don't know. Just a thought.

I see you contacted CustomerCare so that's a good thing. Are you running iOS 6.x on your iPhones? If so, you could try a Network Reset on your phone. That sometimes clears out any "gremlins" that may be in your OS so it can connect reliably, especially if all of the lights on the MicroCell are solid green. However, in doing so you may lose some settings so write down pw's, whatever, just in case.

How do you have the MicroCell set up?

Thanks Otto!
Yes I have reset just about everything on my iphone including network settings, and routers and modem. I am running the most updated iOS version. I even got a new modem from Comcast that I am trying to see if it will help. But as of this morning, that did not help either.
I called AT&T and talked to the support folks, and they are stumped too. The ladies that I have multiple conversations are Kitty and Jamie. They are VERY nice and accomodating, but they are not sure what the problem is either.
So Kitty has a third microcell on the way. I should get it this week.
----
But a question for the forum. Does altitude matter for the microcell placement? I have a functioning cable outlet near a cabiinet in the kitchen that I could easily run the wiring to the top of the cabinet, thus making it about 9 feet high and two feet from a window. Just curious, is there anything inherentley beneficial to putting th MC higher? Thanks much

That's an interesting question that hasn't come up before to my knowledge. My MicroCell is on the edge of a desk next to the window. The router is about 10' away and 4' up. I recently moved the router for the very reason you ask your question, for better coverage. That simple adjustment in height on my router significantly improved the transmission quality for WiFi to the furthest spot away in our house (which is my chair in the family room). I don't know how the signal is propagated with the MicroCell. WiFi is always best high up because the signal goes "out and down" but the MicroCell......? You might want to to an experiment and get back to us. My feeling is that it probably won't help but you never know.
So Alec, back to your question, do you have multiple devices on your LAN and how do you have the MicroCell connected? You may want to consider port forwarding to a static IP. That's what I do and my connection has been rock solid for almost 3 years now even with turning the power off for network reconfiguration (moving the router, cleaning up the cable nest, etc).

Thanks Otto, I just put the MCell, airport express and cable modem up atop the cabinet.... Lets see how it works out.
My Setup is a docsis 3 ipv6 comcast (ubee - formerly arris) modem, A 2013 Apple airport express handling the prioirity mode of the microcell. Separately, I have another cable modem (wired, not wireless) powering an eMac (we love that old computer).
Clients are ipod, three iphones (one old 3g, but the other two iphone 4 and 4s, all updated to current ios
), Direct TV wireless gaming reciever, Wireless printer. Macbook Pro, and another emac occasionaly used.
I have the airport express set up with a "guest" channel and my regular channel, both are password protected. I tested my speeds with the MC and airport express hooked up and it is 55 down and 11 up, Fast!
Not sure how to port forward the set up, hopefully I will not have to go down that road.
Thanks much
A
