In November of 2011, I received a advertisement from Verizon stating that I could upgrade my present Verizon
Wireless Fivespot which is 3G for a Verizon Jetpack 4G LTE Mobile Hotspot MIFI 4510L free. I made the switch and
used it in my home in Nebraska for about a month and a half before going on the road in my motor home heading to
California for the winter. From the start, I have had problems with the MIFI disconnecting from the internet.
Constantly. Access will go from "Local and Internet" to "Local only" or "Connected with limited connectivity".After
fiddling with connect/disconnect which sometimes takes anywhere from a few seconds to a couple minutes, I may
regain a connection. It is very frustrating when trying to pay bills on line or fill out forms, etc. When I arrived
in CA, I went to a Verizon store and eventually got them to order me a replacement. Same problem. I am now on my
third replacement (fourth MIFI) and another replacement is on the way as I write this. I'm a 13 year veteran of
Alltel/Verizon and have not used any other wireless service. I asked the rep at Verizon if I could get the latest
Jetpack 4620L since the 4510L wasn't working. I thought I had an agreement to get one as a replacement with just an
extension of the two year agreement, but then I was told I would have to pay a reduced price for it. I didn't go
for it, so now a 4510L replacement is on the way. Another problem with this device is the constant switching
between 4G and 3G. I've been parked in the Monterey Elks Lodge parking lot since Dec 26th and the light blinks
green when 4G and purple when 3G. It goes back and forth continuously. At one time or the other, all devices that I
have had have had the firmware upgraded at the store and at least two sim cards replaced. Two trouble tickets were
issued, the first lost and I've not been contacted about the second one although it's been a couple weeks since the
second ticket was issued. There seems to be some serious design or manufacturing problems or both with the 4510L.
It looks as if I'm going to be stuck with this device unless I want to just dump it and take my penalty. Is there anything else that I can do?
