I recently went away for 5 days and turned off the power to my router (Linksys WRT54GL), modem (Motorola SB6121) and MicroCell. I got back and powered everything back on, as I have many times before, and noticed that my MicroCell is not working. The Power light is the only light that is lit and it is solid green.
The MicroCell is within 18" of a window with an unobstructed view of the sky, my cellphone gets shotty reception there but the MicroCell has worked for 2+ years in that position so I don't think that is the issue. The MicroCell is at least 2' away from any WiFi source. I've swapped out ethenet cables. And my internet service is otherwise fine.
Here's what I've already tried: I've cycled power numerous times to my various devices in the order suggested here. I tried a hard reset to no avail. I finally deactivated my MicroCell and now that I tried to reactivate it I'm stuck at part one (1) Power Up [Pending]. I'm still only getting the solid green power light. The port on my router that the MicroCell is plugged in to is not lighting up. I plugged the MicroCell power supply directly into the power outlet, same result. I tried to connect priority mode, and can't get my connection to work at all that way... just the power light.
I thought I read that hard resetting these things can brick them? Is that what I'm looking at here?
Any suggestions would be greatly appreciated.

I have not seen proof either way that a hard reset will brick a MicroCell. That's what it's there for, to totally clear out the ROM if something goes awry. I have recommended to folks performing a hard reset at times and have never heard back that it bricked their MicroCell.
The fact that you don't get any lights on at all is bothersome. If you get the same results with the priority setup like to you with the nominal setup, that rules out the router and points to the MicroCell. Could your ISP be having trouble with one of the required ports that need to be open? Probably not but it wouldn't hurt to ask because it sounds like your MicroCell is unable to get to the internet let alone AT&T.

I opened up my router settings (running Tomato 1.28) and and do not see the MicroCell listed at all... so I don't think I can even do much on my end.
My next idea was to deactivate it again and take it to a family members to see if I could get it activated/connected there to provide some more info...

Ok. The ports that need to be opened are: 123 UDP, 443 TCP, 500 UDP, and 4500 UDP, public and private.
IPSec Pass-Through in enabled and Block Fragmented Packets is disabled.
If you can't see the MicroCell in your router's DHCP table then that's your problem.

And again, nothing was changed what so ever other than all of them powering off and powering back on. At this point I'm thinking it was maybe just a coincidence and the MicroCell went. I'm assuming it's possible to get power but something else internal went on it so it's non-operational.

Did the MicroCell get knocked over? And if so, does it rattle if you GENTLY shake it? It is possible that after 2+ years (the same age as mine) it has failed.
Yes, if you can't see it in your DHCP table then it's not there as evidenced by the internet (ethernet) light being out.
We are remodeling right now and my MicroCell has been off and on all week long. It only takes it about 8-10 minutes to come back up and be functional so you just may have a unit that has died

No rattling. However, there is a high pitched, constant, buzzing noise (by noise I mean you can really only hear it when you put your ear about 6 inches away or closer to the top vents) that I don't seem to recall hearing before. I'm going to try it with a whole different setup tomorrow and report back.

Hmmm, a buzzing noise may indicate something is failing but mine has always made a very slight nosie as well but you have to be very close to hear it. Unplug it and let it sit for awhile and then set it up again. You do have plenty of ventilation around it don't you? They do get hot (warm).

It's always had plenty of ventilation, sat on the top of a entertainment system with nothing around it but a light. So I tried setting it up at my dad's house with the same result, solid green power light. So I'm guessing it's the MicroCell. I did notice that when I plugged in the power, there was a spark... significant, very visible and not normal.
I don't think I mixed up the adapters (Input: 100-120V, 50-60Hz, 0.4 A; Output: 12V-1.25A). Could the adapter be the culprit? I have read that before on here caused problems for others but I figured since I'm getting the solid green power light it wouldn't be the issue.

It is possible that the ac adapter is starting to fail. If you replace it make sure you use one with the same ratings as the original and that the polarity is Positive. A slight spark when you plug it in is not good Something may have gotten fried on the inside.
