Netgear AirCard 778AT – AC778AT Around Town Mobile Internet 사용자 설명서

Move your hotspot and your computer or WiFi device to another location. You might be in 
or near a structure that is blocking the signal. Every obstacle (for example, walls, ceilings, 
furniture) between the hotspot and other WiFi devices decreases the signal strength.

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

Make sure that you allow plenty of space around your hotspot to provide the best signal 
reception.

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

To improve your hotspot’s WiFi performance, try the following suggestions:

Try a different channel number. For more information, see 

106.

Check to see whether any hotspot software updates are available. For more information, 
see 

65.

134.

Limit the number of computers or WiFi devices that can connect to the network. For more 
information, see 

83.

The following are additional questions about your hotspot.

No, you cannot replace the micro-SIM card. You can use only the micro-SIM card that came 
with your hotspot.

Data transfer speed depends on the LTE signal strength and interfering radio sources like 
electrical generators or other hotspot WiFi devices. Review the following possibilities:

Check your LTE and WiFi signal strength.

Check the WiFi interference by powering the hotspot off and on to find a better WiFi 
channel.

If the LTE network signal is low, consider using external antennas or cradle the hotspot 
with built-in high- gain antennas.
