Question:
What information do I need to get from my wireless carrier to set up the IPn4G?
Answer:
The APN is required to configure the IPn4G to communicate with a wireless carrier. Some
carriers also require a username and password. The APN, username and password are only
available from your wireless carrier.
Newer units may support an AUTO APN feature, which will attempt to determine the APN from a
preconfigured list of carriers and commonly used APN’s. This is designed to provide quick
network connectivity, but will not work with private APN’s. Success with AUTO APN will vary by
carrier.

How do I reset my modem to factory default settings?

power on the IPn4G and wait until the status LED in on solid (not flashing). Press and hold the
CONFIG button until the unit reboots (about 8-10 seconds).
