Wireless Internet Access - ZyXEL Communications NR2101 User Manual

One of my clients cannot access the Internet anymore. They had access to the Internet (with the
Zyxel Device), but the Internet connection is not available anymore.
Make sure your client is not blocked. You can check this on the Web Configurator (See
1
page 67).
Make sure your SIM card's mobile data is enabled. Check this on the Web Configurator (See
2
on page 56).
If you have set a data limit, make sure you have not reached it yet. You can check your data left in the
3
Web Configurator.
Reboot the Zyxel Device.

The Internet connection is slow or intermittent.
There might be a lot of traffic on the network. If the Zyxel Device is sending or receiving a lot of
1
information, try closing some programs that use the Internet, especially peer-to-peer applications.
Check the signal strength on the Device LCD screen. If the signal strength is low, try moving the Zyxel
2
Device 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 wireless network (for example,
microwaves, other wireless networks, and so on).
Reboot the Zyxel Device.

If the problem continues, contact the network administrator or vendor.
