Nighthawk RAX29 with Verizon LTE extender

[Linda6418]

I can not get my Verizon/Samsung LTE Network Extender to set up and initialize.  I have not contacted my ISP since I don't have total confidence in their customer support.  Has anyone had similar issues or know what changes I should make to my Netgear router for this to work?

[plemans]

1. what modem/gateway is the netgear connected to? 

2. what exact verizon lte extender model is it? 

3. did you contact verizon on help setting up their product?

My Modem: Arris TM822

Verizon 4G LTE Network Extender model SLS-BU103

I did contact Verizon.  Their response was that there was no issue on their end and that the network extender was connected to a router that may not be configured for use with a network extender.

When you log into the rax, are you able to see the LTE extender in the attached devices page? 

[Linda6418]

Yes.  And it shows the IP address as well as the correct MAC address

[plemans]

You could try putting the lte extender into the netgears dmz. 

that'll auto forward all info to the lte extender. 

[Linda6418]

Do I change the default DMZ server to the extender's IP?  Currently the DMZ box asking for a default server is not checked.

[microchip8]

Yes.

And while you're at it, reserve an IP for the extender so you always get the same one whenever it makes a connection.

[Linda6418]

I made both of those changes but that has not helped.  Could my ISP be blocking it in any way?

[plemans]

I'm betting its more something on verizon's end. If its connected to the router and the router is giving it an IP address. 

So its connected, its just not working properly.

What brand and model number of cell phone are you trying to use to connect to the LTE extender?

Does the phone properly connect to the Verizon data network at other locations?

Does the phone not connect to the extender for phone calls or cell data or both?

[Linda6418]

My phone is a Samsung Galaxy S9+ and was connecting fine before.  The problem is not that my phone won't connect to the extender.  The extender is not connecting to the Verizon network.  Verizon says the extender is working properly and that I should contact my ISP.  I don't see why my ISP could make a difference.

[plemans]

You're kind of caught in limbo of is it the router or is it the extender. 

So cheat. Disconnect the router from the modem and power the modem and the extender off for a couple minutes. 

power the modem on and give it a couple minutes. 

Then connect the extender directly to the modem and power it on. 

Give it a couple minutes. 

IS it working? If so, it still can be something in the router. 

No, then it implies the extender is the issue. 

[Linda6418]

I will give that a try.
