Microcell not activating after previously working

I am having some issues with my Microcell.

 

It was previously working for about 2 months. Yesterday morning it began blinking 3G bars green. I unplugged it and plugged it back in, it would not go back to solid. So I called AT&T and they recommended that I remove it from the account and add it back. I did so and now it will not reactivate. I have tried unplugging evertything and plugging it all back in, and doing a hrad reset of the Microcell. It currently is just sitting with the power, network and gps all solid green while the 3G blinks green.

 

Please help! Thank you!

Can you give us more detail on how you have it set up, your hardware, the type of ISP service you have and with whom, etc.

Absolutely.

I have TWC as my cable internet provider (50mbps down and 12mbps up)

I have a Motorola surfboard sb6141 as my modem, a netgear wndr3400v2 router
that has a static ip address assigned to the microcell with ports 123, 443,
500 and 4500 forwarded.

I have the modem feeding to the router and the microcell feeding off the
router.

When I got it from ebay a few months ago it came with the wrong power
adapter, so that was fun to figure out, I have since purchased a universal
power adapter from radio shack that is a 12v, 1.5a.

I have the identical problem.

 

an inability to register a previously functioning mcel after having de-registered it.

 

also having purchased brand new mcells, they won't register either.

 

if you find a way to register your mcell, can you please DM or post me thx.

Try the alternate connection method: modem -> MicroCell. Powercycle both and let it register. If that works, then it's something to do with the router and/or settings because your MicroCell is connected directly to TWC. If you get the same results with a direct connection, then it's probably TWC.

 

TWC did some network hardware upgrades a few months ago which caused the MicroCell to lose connectivity to AT&T (blinking green 3G light). It took a very nice TWC Network Engineer to figure it out and get the hardware fixed (they blamed it on the vendor not using correct settings).The ac adapter should work (12V, 1.25A output is what my old DPH-131 was rated at).

 

I'm assuming that the power, GPS, and ethernet lights are solid green and the only light that is blinking is the 3G light.

 

There's always the possibility that it was defective or failing if you purchased it off of eBay.

I tried hooking it up that way and it still didn't work.

I am waiting for a new power adapter as that may be the culprit yet again.
It sure was last time. I will post the results once I get that delivered.

Blinking green 3G light only? All others a solid green?

Yes, exactly.

Loss of connectivity to AT&T's Mobility Servers. Speed per se is not a factor because all you need is at least 3.0Mbps of stable speed. You might want to run a VoIP test to see if it is a line quality issue.

 

You might want to check with TWC and see if they have done, or are doing any upgrades to their system. Don't ask them about the MicroCell because they won't know anything.

Hopefully Avedis53 will take a look at this. The downstream jitter seems a tad bit high but let me see what he says. Keep in mind that that's just a snapshot of that point in time. Overall it could be worse, or better than that so you need to do it a couple of times to get sort of an average.

 

When you set it up via the alternate method (no router involved) did you powercycle the modem and the MicroCell? Mayb even do a hard reset on the MicroCell?
