One of my WiFi clients cannot access the Internet anymore. They had access to the Internet (with
the NR2101), but the Internet connection is not available anymore.
1
Make sure your WiFi client is not blocked. You can check this on the Web Configurator (See Section 7.5
on page 73 ).
2
Make sure your SIM card’s mobile data is enabled. Check this on the Web Configurator (See Section 6.3
on page 59 ).
3
If you have set a data limit, make sure you have not reached it yet. You can check your data left in the
Web Configurator.

Reboot the NR2101.
The Internet connection is slow or intermittent.
1
There might be a lot of traffic on the network. If the NR2101 is sending or receiving a lot of information, try
closing some programs that use the Internet, especially peer-to-peer applications.
2
Check the signal strength on the NR2101 LCD screen. If the signal strength is low, try moving the NR2101
closer to the ISP’s base station if possible, or try pointing it directly to the ISP’s base station. Look around
to see if there are any devices that might be interfering with the WiFi network (for example, microwaves,
other WiFi networks, and so on).
3
Reboot the NR2101.
4
If the problem continues, contact the network administrator or vendor.
13.5 WiFi Internet Access
What factors may cause intermittent or unstabled WiFi 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 WiFi devices.
To optimize the speed and quality of your WiFi connection, you can:
• Move your WiFi clientdevice closer to the AP if the signal strength is low.
• Reduce WiFi interference that may be caused by other WiFi networks or surrounding WiFi electronics
such as cordless phones.
