Amherst, Ohio - Microcell - Flashing 3G Light

Hello All...

My name is Mike and I live in Amherst, Ohio - Approx 25 miles west of Cleveland...

I do have TWC as my Cable provider...Am using a leased Scientific Atlanta 2100 Modem, Linksys WRT54GS V7 Router and the DPH151-AT AT&T 3G Microcell...

The reason I need a microcell is that I live in an aluminum sided house and the reception is terrible inside the house.  For my work, I have recently been required to attend many weekly conference calls and need a solution that provides solid phone reception.

A couple years ago, when AT&T had the Samsung Galaxy Tablet/Samsung Galaxy SII deal, my wife and I opted for it and also spoke to the local AT&T Store manager about our reception issues...In comes the AT&T 3G Microcell...

I took it home and activated it with no issues...Over the course of a week, it did provide a boosted signal for my smartphone, but decreased the reception of the 2 Nokia 6010 phones in use at that time...

As I was the only one affected, I elected to take down the microcell, box it up and put it away in the closet...

Approx a week ago, I upgraded my pone to an LG G2 and got my wife, who is resistant to change, to start using my Samsung Galacxy SII...She now loves it...

Net, Net is that her reception is almost non-existant and mine is 1-2 bars at most...

Pulled out the Microcell and I had never disconnected it, so disconnected it and went through the activation process again ...All was fine until it came to the 3G light...

This configuration was Modem>>Router>>Microcell...I went through all the troubleshooting listed several times to no avail...

Changed configuration to the Modem>>Microcell>>.Router and same issue...The dreaded flashing 3G light!!!

In reading many of the posts, I believe the issue to be TWC blocking port 4500, but is there anyway I can test for sure???

Also, in looking into alternatives to the Microcell, I ran across the Cell-Fi...A bit of a pricey solution at $575...Do you think AT&T would split the cost with me to buy into this solution???

Any recommendations would be greatly appreciated...

Thanks In Advance...

Mike...
