Troubleshooting a 3G or 4G Wireless Connection

This should include the step to troubleshoot cellular 3g and 4g connections.

First of all, what equipment are we trying to troubleshoot?

 

1)Connections involving routers

If, there is a router in picture head over to this article and try the simple ping test to determine whether the problem lies. Is it the connection between your computer and router? Or is it somewhere between the router and modem?

  A) If you can't ping the router:

      1) Unplug the router for 10 seconds and than plug it back in. Wait till all 4 lights have come back on and than try pinging again or sending/receiving for that matter.

     2) Turn the computer TOTALLY off and than restart

     3) Unplug the modem from the router and plug it into the computer. Install the correct software that would've come on a cd with the device. Skip down a couple lines to view some more detailed instructions.

      

  B) If you can ping the router but nothing further try the following.

      1) Unplug the modem from the router and turn the router off for 10 seconds. Plug the modem back into the router and reboot the router. Wait till all 4 lights come on than try pinging again.

      2) Unplug the modem from the router and insert it into the computer. We'll have to install the proper software before we can use the modem. Below is a list of modems and what needs to be installed etc...

     -------

        UML175 - This software can be found by inserting our cd, pressing run, Going to Software > UM175 VZ Modem > Windows > VZAM_7.2.1_2420b_Pantech_UML175. Double click on the file and it will guide you through the installation process. Once done, open the icon on the desktop and try connecting.

        UML290 - This software can be found by inserting our cd, pressing run, Going to Software > UML290 VZ Modem > Select your OS type > click on your application. It will guide you through the installation process. Once done, open the icon on the desktop and try connecting.

        Verizon 4G LTE USB Modem 551L - Insert the cd that came with the device. Allow it to install and than try connecting.  

       Sprint USB modems - Insert our cd and press run. Go to Software > Sprint > Agape_Sprint_SmartView_2_50_0118_setup. Click on the file and let it install. Once done, go to the desktop and click on the Sprint Smart View and try connecting.

     ------

       3) If it throws an error saying that it cannot find the modem make sure the modem is inserted. If it is inserted, unplug it, reboot the computer, plug it back in and than try again. If it stills says the same thing it's very likely the modem has gone bad.

       4) How many bars of signal does it show? Enough?

       5) Check for an outdated Antivirus and remove it.
On Windows 7 and Vista go to Control Panel>System Security>Action Center, Drop down the security bar and see what antivirus program it shows. Go to Control Panel>Software>Add/Remove programs and uninstall.

2) Connections involving MiFi devices. The small device about the size of a large sandwich that creates a wifi hotspot for you to connect to.

   A) Try rebooting the device. Unplug it and remove the cover located on the bottom of the device. Remove the battery for 10 seconds and than slide it back in.

   B) Is the device plugged in and fully charged?

   C) What colour is the light? How fast is the light blinking?

       The colour codes for the Verizon devices are:

         

      The colour codes for Sprint are:

       ● Blue single blink – Device is connected to network and Wi-Fi is ready.
       ● Blue double blink – Data is being transferred.
       ● Amber blink – Network is not ready. (Mobile broadband is disconnected, no signal is
           available, or Wi-Fi is asleep.)
       ● Alternating orange and amber blink – Software updates being applied.

    D) Try tethering the device to the a computer and setting it up with the instructions that came with the device.

    E) Was there any thunderstorm in the area recently?

    F) Is your subscription current?

    G) If the lights don't come on at all it's very likely the modem or battery has gone bad. Most cell-phone chargers are compatible with the Mi-Fi devices so try plugging a cell-phone charger into the device and see what happens.

 

3) USB modems. These are the simple modems that plug into the common USB port of any computer. They give the most trouble because they get banged around more than the stationary equipment.

    A) Unplug the modem and reboot the computer. Insert it and try again.

    B) Uninstall the software and reinstall.

          1) For Verizon

                 Go to Control Panel > Programs and Features and find VZ Access manager. Right Click on it and press uninstall. Once done uninstalling go back to the same list and look for something down the line of UML175 device driver or UML290 device driver and uninstall it as well. Reboot and than re-install

          2) For Sprint.

                  Go to Control Panel > Programs and Features and find Sprint Smart View. Right Click on it and press uninstall. Once done uninstalling go back to the same list and look for something down the line of Pantech device driver and uninstall it as well. Reboot and than re-install.

    C)  Check for an outdated Antivirus and remove it.
              Go to Control Panel>System Security>Action Center, Drop down the security bar and see what antivirus program it shows. Go to Control         Panel>Software>Add/Remove programs and uninstall.
