3G Microcell loss of connectivity issue
So, I have had a 3G Microcell in my house for the past 2-3 years and it has worked fairly well, with the occasional outage due to network issues, but the cell itself seems to have been fine through that time.
Recently,within the past week,I have noticed that it keeps dropping out on a frequent basis. LastFriday I started watching it closely by doing a continuous ping from my phone to the Google DNS server, which I do whenever I want to test Internet connectivity. I noticed that every 15-20 minutes the ping would stop and then the AT&T M-Cell notification on the phone would go to searching and the bottom light on the microcell would start flashing. This would go for about 2 minutes then recover.
From my IT/networking background this sounds like a classic memory leak.
I worked with AT&T support on Saturday and we finally did a hard reset using the button on the microcell. This seemed to fix it for about 36 hours, but now, this morning it is back to the every 15-20 minute reset.
Any ideas here? Does anyone know if a recent firmware upgrade was pushed that might cause this? Is anyone else having similar problems?
