Tips 
Place your Mobile Wi-Fi where you get the strongest signal. The more windows a room has, 
the better the signal and upstairs will generally get a better signal. You can then be online 
wherever you like nearby. 
If the Mobile WiFi is placed in an environment with poor ventilation, it may overheat after 
extended use. When the Mobile WiFi overheats, it will switch off and disconnect from the 
network automatically to protect itself. If this happens, place the Mobile WiFi in a 
well-ventilated location, then restart the Mobile WiFi. 
If you are experiencing difficulties using the Mobile WiFi, try the following: 
 See help on the web management page.  Restart the Mobile WiFi.  Restore the factory defaults.  Contact your service provider.  
						

							20  Frequently Asked Questions (FAQ) 
What can I do if the Client cannot access the Internet? 
5.  Check and ensure that the Client is connected to the Mobile Wi-Fi properly. 
6.  Check the power status to ensure that the Mobile Wi-Fi is powered on. 
7.  Check the signal strength to ensure that the area is covered by the network. 
8.  Check that the network mode is correct. For details about network modes, see Mobile 
Network Settings on the management page. 
9.  You must configure the correct peer-peer protocol (PPP) user name and PPP password 
when you access the Internet through the Mobile Wi-Fi. Check whether the user 
name and the password are correct, and see Profile Management on the 
management page for details.   
10.  If the DHCP server is disabled and the Client obtains the IP address dynamically, the 
device cannot access the Internet either. In this case, you need to change the mode to 
manually assign an IP address. See DHCP Settings on the management page.
