Reset Button Press and hold to restore your 4G hotspot to its factory settings ☆ If you forget the user name, password or SSID for your 4G hotspot, try restoring the device to its factory setttings 8. WPS Button Installation WiFi Connection The default SSID (WiFi network name) and WiFi network key are printed on the 4G Hotspot Label We strongly recommend that you change the default SSID and WiFi key to keep your data secure ☆ You can manage your 4G hotspot through the Web Interface at http://192.168.0.1. The default username and password is admin. Click the online help on the web interface to learn more about your 4G Hotspot. ☆ After installation of driver, you can access to Web Interface http://192.168.0.1 Charging Please only use a charger that is compatible with your 4G Hotspot. The use of an incompatible charger may cause the device to malfunction, fail, or could even cause a fire. Such use voids all warranties, whether expressed or implied, on this product. ☆ The charger is an optional accessory. To buy a charger, please contact an authorized retailer. Connecting to the Internet Using an LTE, 3G, network The 4G Hotspot’s management parameters have been preset according to your operator’s requirements. If data is transmitted, the 4G Hotspot will automatically connect to the internet. If data is not transmitted for a period of time, the 4G Hotspot will automatically disconnect from the network connection. ☆ You can log in to the web management page follow below steps: Log into Web Management page → Network Setting → Connection Mode . Logging into the Web Management page ☆ Make sure that the connection between the 4G Hopspot and the device used to access the Internet, is working normally. ☆ Open the browser on your device and enter http://192.168.0.1 in the address box. ☆ Enter your username and password to log into the web management page. If you have any difficulty please contact customer care. Please note: The default username is admin The default password is admin Wi-Fi Sleep Mode (Battery Saving Mode) The Wi-Fi device has a mode that allows the device turn off automatically if there are no devices connected to the 4G Hotspot (via Wi-Fi or USB) for a period of time . - This mode allows the device to go to “ Wi-Fi Sleep ” Mode to save battery life. - The device can be switched back on by pressing the power button. - The preferred timing can be set by selecting “Wi-Fi Sleep”, and choosing the options shown below screenshot and steps to get to “ Wi-Fi Sleep ” Mode . Log into Web Management page → Advanced Settings →Power Save → “ Wi-Fi Sleep ” Mode Restoring to Factory Settings If you forget the username, password, or SSID you have set, you can restore the settings on the web management page to the default factory settings. To do so, simply press and hold the RESET button until the 4G Hotspots restarts. Changing SSID and password It is recommended that you change your 4G Hotspot’s SSID and password before you use it. The default SSID and password are printed on 4G Hotspot’s label, in the battery slot of the device. Enable SD card sharing * In HTTP Share Mode, the device only supports FAT/FAT32 file system. * HTTP Share Mode: Share SD card via web browser. The removable drive mapping of SD card via USB port will be disabled. * USB Access Only: By the removable drive mapping, user can access SD card *via USB cable only. The web page of sharing SD card will be disabled. * Path to Share: You can input the sharing path, such as /Picture. By typing only, a slash in Path to Share filed, you agree to share entire SD card. * Path to Share can't be a dot, and can't contain following characters: < > " ' & + / \: * | # ? ~ ` SMS Tips: ◇ Why isn’t my 4G Hotspot responding? Try restarting the device. If that doesn’t work, restore the device to its factory settings ◇ Why can’t I connect to my 4G Hotspot sometimes? To save Power, your 4G Hotspot’s WiFi auto off feature is designed to turn off WiFi when there haven’t been connections for a while. You can press the power button to turn on WiFi again. Alternatively, you can disable this feature, although this might impact battery life, Log in to the web interface and disable the WiFi auto off feature. ◇ Why won’t my 4G Hotspot connect to a network even though all the settings are correct? The PIN verification feature might be enabled. You can disable this feature if you find entering the PIN regularly inconvenient. ◇ Why can’t I access the Web Interface at 192.168.0.1 ? This is likely due to an IP address conflict when the 4G Hotspot assigns itself a new IP address. Please try 192.168. 2.1 in this case. ◇ Why won’t my 4G Hotspot power on? Your battery is probably out of power. Charge your 4G Hotspot for a While and Power it back on. ◇ Why did my 4G Hotspot power off all of a sudden ? Your 4G Hotspot may overheat when you use it continuously over a long period of time, and thereby trigger its automated protection system. WiFi will be turn off and your 4G Hotspot will power off if this occurs. Please ensure the device is properly ventilated and cooled before you power it on again.
