IMPORTANT
Configure the PocketPORT BEFORE attaching the 4620L.
The default APN is vzwinternet (private dynamic IP addresses)

After writing the configuration parameters, power-cycle the PocketPORT.
Install and run the MiFi 4620 update utility from the link below on a Windows PC with the 4620 connected via a USB cable to the PC. This update may take several minutes to complete and your 4620 will restart several times.

*** Once updated, you must make the following configuration changes on the 4620 after connecting to it via WiFi (http://vz.hotspot):
Network>WWAN>Auto-connect = Manual
Advanced>Settings>USB Tethered Mode = Enabled
Advanced>Settings>Automatic Shutdown = Never
After changing these settings, power-cycle the JetPack. See the 4620L's User Guide for more information on changing the JetPack's settings.
There must be no Wi-Fi devices connected to the 4620L when the PocketPORT is attached. Note that the PocketPORT will NOT show as an active user on the 4620L's display. |
