Sounds to me like either the tower you connect to went down, was overloaded or something along those lines. I think it's ridiculous, however, that the network will dump someone already on a call.
I remember back when Cells were so new. You could only talk for like 10 minutes at a time, because the network would cycle through as the network filled up. Dumping someone who'd been on a long time to allow connection by someone else. You hardly ever see that anymore however I've seen it here locally. (out in the rural areas)
I've had a network extender for over a month. About 10 times I would find the Sys light blinking red in the morning and would have to recycle the power and wait 10 minutes. But other than that it has been reliable.
Today it locked up on me and would not let any Verizon phones in the area send or receive calls. Had 4 bars but #48 failed. Called Verizon tech support and they said to recycle the power (I knew that would fix it).
Sounds similar to your problem Art. This is a bigger problem than the Sys light flashing red because this will completely prevent my neighbors from using their phones until I cycle the power!
i've had to cycle the NE a few times as well and it can be frustrating as acquiring the GPS signal seems to take way too long. My neighbors are the least of my worries though ..
when this thing works it works great, the little hiccups can be frustrating, especially when they happen when you REALLY need that signal.
When my Sys LED is blinking red there is no service and my phone doesn't show any bars.
When the NE locked up today it had all LEDs blue (as normal) and my phone had 4 bars (as normal) but I could not receive or make calls.
Those are the two types of problems I've encountered.
The Network Extender has four available channels:
If your neighbors are using the signal also they might be using the voice channels before you...
Power LED Indicates that the base station is receiving power. No illumination indicates there is an issue with the power supply or power connector.
System LED Indicates that the base station is properly communicating with the Verizon Wireless network. This light will blink red while establishing the initial network connection. Continuous red indicates an abnormal condition.
GPS LED Indicates that the base station has received a valid GPS signal. If the GPS LED light is red, the internal antenna may not be able to detect a GPS signal, and installation of the external GPS antenna may be necessary. (Refer to the product User Guide for details.)
WAN LED Indicates that the base station has detected a valid Ethernet connection. Blinking blue LED light indicates data communication.
