Netgear AirCard 778S (Virgin Mobile) – NETGEAR® MINGLE™ Mobile Hotspot 사용자 가이드

●

Move your device and your computer to another location — you may be in or near a
structure that is blocking the signal. Every obstacle (for example, walls, ceilings,
furniture) between the NETGEAR Mingle Mobile Hotspot and other wireless devices
decreases the signal strength.

●

Place your device in a centralized location, as high as possible in the room.

●

Make sure there’s plenty of space around your device to provide the best signal
reception.

●

Keep your device at least 3–6 feet away from electrical devices that generate RF
interference (for example, microwaves, TVs, 2.4 GHz cordless phones, cellular phones,
baby monitors, wireless speakers). If you’re not using these electrical devices, turn them
off.

●

If possible, place your devices so that the signal passes through open doorways or
drywall, as opposed to concrete, brick, metal, walls with insulation, and so on.

●

If you cannot obtain service, contact Virgin Mobile — a network or account problem may
be preventing you from obtaining service.

Improving 3G Network Service

The PRL (Preferred Roaming List) is an account configuration item set by your service provider.
It controls the radio channels and network carrier used by the 3G modem.

To check for these updates:

1. Log in to the home page. (See
