Verizon MiFi 4510L Mobile Hotspot on 3G (EVDO) & not switching to 4G (LTE)? Here's a solution.

I have a Verizon MiFi 4510L Mobile Hotspot and recently I experienced the issue where my device was stuck on 3G (EVDO) and was not switching to 4G (LTE) even though I knew that 4G service was available. The device indicator light was blinking purple/violet instead of green. This is apparently a known problem for this device. So, if your device isn't switching to 4G, it's not defective. Resetting the device won't do anything.

Here's how I got it back to 4G (LTE):

  • Connect to your MiFi
  • Log in to your MiFi by typing this URL into your browser:
  • Click on "Setup Wizard"
  • The default password is "admin" (unless you've changed it)
  • When it asks you to set up a new password, click "cancel"
  • Now you'll see that you have several new menu options at the top red horizontal navigation bar: Home, Wi-Fi, LAN, WWAN, Security, Advanced

Now, you'll want to click on WWAN -> and then go to the "WWAN Settings" at the bottom of the page.
  • Under the WWAN Preferred Mode, select "LTE only"
  • Then, click "apply" and the device will reboot.
My understanding is that this is a temporary fix. Therefore, you may need to do this periodically if you move into areas where you only have 3G coverage. The MiFi could have a tendency to get "stuck" in 3G mode and it needs to manually get moved back to 4G using the steps outlined above.
