The Internet connection is slow or intermittent. 

Step 1

 

There might be a lot of traffic on the network. Look at the LEDs, and check Section 1.6. If the 
LTE Device is sending or receiving a lot of information, try closing some programs that use the 
Internet, especially peer-to-peer applications. 

Step 2

 

Turn the LTE Device off and on. 

Step 3

 

If the problem continues, contact the network administrator or vendor, or try one of the 
advanced suggestions. 

----End 

Advanced Suggestions 

Check the settings for QoS. If it is disabled, you might consider activating it. If it is enabled, 
you might consider raising or lowering the priority for some applications. 

25.5 Wireless Internet Access 

What factors may cause intermittent or unstable wireless connection? How can I solve this 
problem? 

The following factors may cause interference: 

 

Obstacles: walls, ceilings, furniture, and so on. 

 

Building Materials: metal doors, aluminum studs. 

 

Electrical devices: microwaves, monitors, electric motors, cordless phones, and other 
wireless devices. 

 

To optimize the speed and quality of your wireless connection, you can: 

 

Move your wireless device closer to the AP if the signal strength is low. 

 

Reduce wireless interference that may be caused by other wireless networks or 
surrounding wireless electronics such as cordless phones. 

 

Place the AP where there are minimum obstacles (such as walls and ceilings) between the 
AP and the wireless client. 

 

Reduce the number of wireless clients connecting to the same AP simultaneously, or add 
additional APs if necessary. 

 

Try closing some programs that use the Internet, especially peer-to-peer applications. If 
the wireless client is sending or receiving a lot of information, it may have too many 
programs open that use the Internet. 

What wireless security modes does my LTE Device support? 

Wireless security is vital to your network. It protects communications between wireless stations, 
access points and the wired network. 

The available security modes in your device are as follows: 

 

WPA2-PSK: 

(recommended) this uses a pre-shared key with the WPA2 standard. 

 

WPA-PSK: 

This has the device use either WPA-PSK or WPA2-PSK depending on which 

security mode the wireless client uses.
