Troubleshooting
If you can’t connect to the Internet via your wireless network 
a) Make sure your router is connected to a power socket.
b) Make sure Wireless Network is activated on your computer.
c) Make sure you have coverage for mobile broadband.
d) Make sure your computer is not located too far from the router.
e) Check that you have entered the right 
network name (WLAN – Name) 
and 
security key (WLAN – Key).
These are found on the label on the back 
of the router.
If you feel that you are not getting the best possible speed
a) Place your router as close to a window as possible, for better coverage.
b) Move your computer closer to the router for improved speed.
c) If many people are connected simultaneously the speed may be lower 
when you surf. It may therefore be a good idea to wait until fewer people 
are connected before downloading large files.
If your connection jumps between the 2G, 3G and 4G networks
In the setup management for the router (see preceding page) you can lock your 
router to a particular network (can only be done when you are not connected):
Select 
General Settings 
in the menu to the left and then I
nternet settings
. 
Under 
Data Connection, 
next to
Network Mode 
you can then choose between 
AUTO, Only 4G, Only 3G
or 
Only 2G.
