Can I have the model number of the TP-Link device? You can find it on the device's bottom label.

Please also show us how is the TP-Link connected to the Juniper router, are there any other switches or extenders?

How did you configure the TP-Link device? Please provide more details then we may understand it better.

You can also follow this guide to do some basic troubleshooting:

What should I do if I fail to configure TP-Link Access Point?

@christophercata 

Is the model EAP245? AC1750 is not the model, please check again. As you can see from the TP-link official website, when searching for AX1750, there are EAP245, EAP265HD, etc.

Meanwhile, can you please show us the network layout in detail? How is this AC1750 connected to the network? Network cable to AC1750 directly? No modem or anything?

Do you have a stable connection when connecting a computer directly to the network cable? Please be sure that is confirmed and you do have a stable connection.

Since you are inquiring about a product that belongs to the business category, I will transfer your thread to our business community, and others would suggest further.

the AP is connected Via POE injector to port GE0/0/5 of the juniper SRX300

I have a stable connection to the internet as i am Part of the ISP that provided the Link for the site.Configs of the juniper have been checked by our core team and we are still unable to make the AP work .

The juniper Dishes out DHCP between 192.168.1.150 -192.168.1.200

The Omada EAP is usually plug-and-play, if you get no internet access from the EAP, please firstly confirm the main Router is working fine.

Then check the points below and see if it helps:

1) Ensure the EAP is hardwired to the Router via an Ethernet LAN cable, use a standard CAT5 above cable for the connection. 
     Usually we can see a corresponding LED light up on the Router.

2) Test the EAP’s SSID with other wireless clients, eliminate the issue is from a specific client.

3) Check the IP info on the wireless clients.
     To access the Internet, the clients need to get Default Gateway (Router) and DNS Server from your network through the EAP.

4) Unplug the EAP, and connect a PC instead to the Router with the same Ethernet cable, check the IP info obtained on the PC and confirm it can get internet access.

5) Reset the EAP: with the EAP powered on, use a pin to press and hold the reset hole for about 8 seconds until the LED flashes green-red-yellow to factory default settings.

6) Repeat step 1)-4) if you still get no Internet access from the EAP.

If it still doesn’t work, contact TP-Link support with the above results for further assistance.
