Awesome when it works; usability issues; 4 have died on me
on April 17, 2013
I really want to say the device works; I really do. On the surface it works, but complications have turned it into a nightmare.
-Works as advertised* (up to 10 devices all running on blazing fast LTE)
-USB tethering too
-Gets about 4 hours battery life with light LTE usage. Heavy usage I get around an hour.
-Nice push button interface with OLED display. Lots of useful information without accessing the internal web panel.
-Has a tendency to go "Dormant." Google: "4620L too dormant to use." If you don't have a application on your computer (i.e. a ping, downloading something, ect..) continuously accessing the internet, the MiFi will enter a "Dormant" state. Most of the time this isn't an issue, but it frequently doesn't leave the Dormant state. This leaves you with a dead internet connection and you have to power cycle the device. This happens frequently when I'm streaming online music; the connection will die, because of the burst nature of the traffic isn't enough from keeping the 4620L from going to sleep.
-Obsolete Single band LTE. Only supports the 700MHz Upper C Band. Verizon is now deploying LTE on the 1.7GHZ AWS Band as well as the 700MHz Upper C Band. The newer MiFi 5510L supports both bands and will be the better device moving forward.
-Charge Deficit. When your uploading large files on an LTE connection, the battery with discharge even if it's plugged in (i.e. the MiFi consumes more power than provided by the AC charger). The MiFi doesn't seem to accept high current charging, so this is a tremendous problem for me. I constantly find my MiFi in a "fail safe" battery protection mode after uploading ~1GB of data (i.e. the internet connection is dead again).
-Mandatory over the air Firmware upgrades. This thing will hold your 4G internet connection hostage until you click okay for the firmware updates Verizon pushes onto it.
-These 4620L's die like flies. I'm on the 3rd warranty replacement within 6 months! They usually die during a botched over the air firmware upgrade. The net effect is that I've seen 4 of these MiFi's and I'm beginning to think I'll see 10 of them before the original warranty period expires...
