3G microcell "network" light blinking red overnight
I have an older microcell, white model 151 (approximately 5 years old).
Every night for the last week or so the microcell as been going offline and when I get up in the morning the "network" light (with the 5 signal-strength bars) is slowly flashing red. The other lights (power, ethernet, and GPS) are still solid green.
After power cycling the microcell, all the lights return to normal (solid) and I can make & receive calls without a problem, until the next morning.
Is this a sign that the microcell is dying? Is there a problem with my local network configuration that's blocking the Microcell's communication? I did get a new router a few weeks ago, but I don't think the Microcell issues started right away after that. I checked the Microcell network guide and I believe my router is configured correctly (all ports are allowed, etc). When I power cycle the Microcell it seems to link to AT&T just fine.
I haven't been able to figure out if the Microcell is going off after X number of hours, or if it happens at the same time every night.
