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.

Frequently Asked Questions (FAQ)

What can I do if the Client cannot access the Internet?

1. Check and ensure that the Client is connected to the Mobile Wi-Fi properly.

2. Check the power status to ensure that the Mobile Wi-Fi is powered on.

3. Check the signal strength to ensure that the area is covered by the network.

4. Check that the network mode is correct. For details about network modes, see Mobile Network Settings on the management page.

5. 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.

6. 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.

7. Check that the network adapter of your Client runs properly.

8. If the problem still persists, please consult you network operator.

What can I do if the Client cannot access the WLAN?

1. If there are interferences or shields near the Mobile Wi-Fi, you can adjust the position of the Mobile Wi-Fi.
2. Check and record the following settings of your Client and your Mobile Wi-Fi: SSID, WEP type, and key. The SSID of the Client must be ANY or the same as that of the Mobile Wi-Fi. The WEP type and key of the Client must be the same as that of the Mobile Wi-Fi. Otherwise, you need to change the settings.
3. Check whether the WLAN MAC filter function is enabled on the Mobile Wi-Fi. If the function is enabled, ensure that all relevant parameters are set correctly. See WLAN MAC Filter on the web management page for more information.

What can I do if I forgot the default IP address of the management page?

Restore the factory defaults and enter http://192.168.1.1 in the address bar.
