If you are unfortunate enough to encounter this error, here’s a little insight. The documentation for the Verizon Novatel 4510L MiFi 4G Hotspot makes no mention of what I’m calling the Blue Light of Death. You will find mention of a red LED, yellow, green, purple, white, and various flashing combinations of the above – but not one sentence about a blue light!
Well here’s the deal – a blue light is bad. Really bad. The first 4G MiFi I picked up from the Verizon store was DOA. I should have been a a little more wary when the sales agent who activated my 4510L said, “a blue light? That’s strange. I wonder what that means. I don’t see it in the manual.” After taking is home, here’s what I discovered:
So if you see a blue light when you’re still in the Verizon store or when you get it from the courier – immediately refuse it and send it back. It’s no good.
Now for the good news. This device, when you have a working one, is awesome! I’ve been conducting various speed tests around Washington, DC and the speeds while connected to the 4G network are incredible. The device even works well when moving, though I did once experience signal loss when crossing a bridge between counties in a DC suburb.
I am also impressed with the WiFi side of the device. It puts out a very strong signal that rivals that of my Airport Extreme Base station and my Verizon Actiontec wireless router. The battery life is also very good. For a device that is smaller than a cell phone, I’m surprised it can send and receive a 4G LTE signal while simultaneously sending and receiving a WiFi signal for several hours without having to recharge. Incredible.
The one major drawback is the USB implementation. You can’t tether the device to your laptop and use it like a USB cellular device. You also can’t use the included USB cable to charge the device. Hopefully a firmware update will make that feature available in the future.
