Introduction

If you’re having trouble connecting a WiFi enabled device to a Mobile Hotspot, or can’t use the Mobile Hotspot to access the Internet, check out our troubleshooting solutions.

Can’t connect your WiFi enabled device to the Mobile Hotspot?

Please make sure that your:

  • Mobile Hotspot is turned on (the power LED light will glow a steady green).
  • WiFi-enabled device is within range of the hotspot (approximately 30 feet or less).
  • WiFi-enabled device lists the Mobile Hotspot's network name (i.e. SSID) in its list of available WiFi networks.
  • WiFi-enabled device is instructed to connect to the Mobile Hotspot.

Can’t find your Mobile Hotspot network name when you try to connect your WiFi enabled device?

  • Turn on the Mobile Hotspot, then see if the LED lights are lit the correct color.
    • A blue LED indicates the unit is roaming and should connect normally.
    • A red blinking LED indicates that the power is critically low.
      • Charge the battery with the wall charger. Please note that the power indicator will be solid amber during charging, and you can use the device while it's charging.
    • An amber blinking LED indicates a modem error.
      • Turn the unit off and on — green or solid amber LED (on charger) indicates the unit is normal.
      • Turn off the unit, remove the battery and turn it back on — green or solid amber LED (on charger) indicates the unit is normal
      • If problem persists, move to another location and repeat the previous step
    • If you have a green blinking LED:
      • Press the Power button (note: you’ll have to reconnect any WiFi device to the 3G Mobile Hotspot).
      • Use the Power Management feature in the Administration screens to change when the 3G Mobile Hotspot goes into idle or shutdown mode, by typing http://hotspot.settings, or http://192.168.0.1 in a browser window, logging in as Administrator.
  • Confirm you’re within range of the Mobile Hotspot.
  • Reset the device if the network name is set to be invisible or if you’ve forgotten its name. Find the steps for resetting the device in your user manual.

Note: if you reset your Mobile Hotspot, all settings will be restored to the original factory default values, including your Mobile Hotspot's network name (i.e. SSID) and the default password (or default WiFi Key). The SSID and WiFi Key can be found on the sticker on the bottom of your Mobile Hotspot. 

Your computer doesn't always recognize your Mobile Hotspot?

Set your laptop or WiFi enabled device to automatically connect to the Mobile Hotspot. This ensures that your Internet connection will automatically be re-established. Otherwise, simply reconnect your laptop or WiFi enabled device to the Mobile Hotspot. 

You can connect to your Mobile Hotspot, but not to the Internet?

If you received an error message when trying to use your Mobile Hotspot to connect to the Internet, or simply can’t browse web pages, make sure that your:

  • Laptop or WiFi enabled device is within range of the Mobile Hotspot.
  • Mobile Hotspot is connected to the Internet.
  • Mobile Hotspot or Mobile Hotspot battery is charged.
  • Mobile Hotspot isn’t in hibernation mode.
  • Device is activated.
    • If the administration pages display a message that the device isn’t activated, you can start an activation session through the menu: WWAN > Configuration > Activate Device.
    • Once activated, it will connect automatically if 3G-Auto Connect is enabled (this is the default setting. You can verify by going to: Advanced > Advanced Options > 3G Auto Connect). Otherwise, push the connect button on the WWAN > Diagnostics page to connect to the 3G network.
  • Web browser is correctly configured.
    • Internet Explorer Users:
      • Go to Tools > Internet Options > Connections tab.
      • Press the Never dial a connection radio button.
      • Press the Settings button.
      • Make sure the Use a proxy server for this connection isn’t checked.
    • Mozilla Firefox Users:
      • Go to Tools > Options >Advanced > Network tab.
      • Press the Direct connection to the Internet radio button.

Also make sure that:

  • You have sufficient signal strength.
    • If the signal shown in your 3G Mobile Hotspot User Interface is low, move to another location with better coverage. This error sometimes results in error code 668 (no signal), which can be viewed in the WWAN > Diagnostics page of the User Interface. View available coverage maps
  • A firewall or an Internet security application isn’t preventing Internet access.
    • Certain security applications may interfere or restrict your access to the Internet. Contact the software manufacturer for assistance configuring the software to allow connection. 
  • Another network isn’t active, by disconnecting the LAN Ethernet cable.
  • Your account is activated (call us at 1-866-206-2182 to verify).
