NVR not getting online

[Schrute]

Hi all, I installed a Dahua system with N52B3P4 nvr and all worked fine with my lousy dsl thats only available on my road. Recently I added a T-Mobile WiFi cell tower. Of course my system couldn't be found so I ordered a dongle and tried to connect it wirelessly. I tried but the nvr did not see the dongle so I ran Ethernet line to the T-Mobile tower but I still can't see my cameras. What am I doing wrong? TIA

Even though the NVR's run Linux, USB dongles to give WiFi typically are not supported.

You may have issues with T-Mobile blocking incoming connections to your network. Cellular connections often do not allow port-forwarding.

Of course my system couldn't be found

Could this be subnet problems? What address is your tower using, what is your NVR set to?

Sorry, over my head, i find this setting in the network area on Dahua? What should it be set to? I wonder if TMobile would/could help if I call?

How do you currently access your NVR? From it's own screen and mouse?

When you said

When you say "I ran Ethernet line to the T-Mobile tower" do you mean you ran a cable from the NVR to the T-Mobile modem/router in your house?

Yes

Yes

OK, so who set it up with that "lousy dsl"?

As alluded to previously by @Perimeter , could be that the T-mobile router's LAN is on a different subnet than the NVR's LAN.

Using the mouse on the NVR, go to the NVR's network settings and see if the NVR is set to "DHCP" or if it has a static IP assigned.

Yes

Also FYI, If you plan on using typical port forwarding to see your NVR from outside of your home, you wont be able to with the T-mobile home wifi appliance

That was going to be in my post #637 as we move along is those teensy, weensy baby steps.....

What if I add a mesh router that I previously used and own at the TMobile tower and plug the nvr into that instead?

Dsl was the only internet available at the time

Yeah if I recall on my foray into that solution for my lousy Comcast connection, the T-Mobile unit was using a 192.168.12.1 address. Likely his previous router was doing DHCP on 192.168.1 or .0

But first, please answer a previous question:

"Using the mouse on the NVR, go to the NVR's network settings and see if the NVR is set to "DHCP" or if it has a static IP assigned."​

[bigredfish]

Bingo

 

[TonyR]

Assuming you're still plugged into the T-Mobile, change NVR to DHCP, save it, count to 30 then see if that LAN IP in the NVR changes...report back.

 

[Schrute]

The DHCP is greyed out and not able to toggle on
