This is the second time my Samsung LTE Extender has rebooted at 04:30 EDT and become stuck at step 11a (which according to the manual, means it's trying - and failing - to download updates). The last time this happened, it was down for five days before service resumed. According to Verizon support, it was an issue affecting multiple customers, but they didn't say more than that. It's currently stuck in a reboot cycle, and I'm not sure when (if?) it will go back to normal.
I am hoping this is not a persistent problem. I rely on this device for phone service in my area! Are any other users seeing this too?
