I was using sprint wireless before this,was on 3G which was working ok.Found verizon had 4G in my area and decided to try it.Speeds are in 18 to 20 mhps which is better than my old 1mhps from sprint.When i installed the MiFi it went straight to 4G and been working like a charm.Signal stays up and i am running 2 computers on network and see no trouble.I am very pleased with this set up.Also the new MiFi 4510L works with the charger plugged in and it has not shut down once.
