NetGear Nighthawk AC1900 Cabel Modem Router Blocking apps

I was in need of a new modem/router and purchased the nighthawk ac1900 c7100v. However now i'm having a weird issue with running programs on my pc that require internet access. I'm not the greatest when it comes to diagnosing internet related issues though but these problems didn't exist with my previous modem. Here is whats happening

On my laptop connected via wifi , i go to start a program (fusion 360 cad) and it just sits there and won't load. No errors

I also have a golf simulator that requires internet access, same problem only it tells me i don't have an internet connection

I've even seen this same problem with an app on my cell phone, not allowing it to load fully while connected to the wifi

Weird part is , i have perfect internet connection to browse the web.

I have found a fix to this however its only temporary. If i restart the modem then everything gets access perfectly fine for the day. So my question is, what could be changing when the modem is reset? And why does it seem to eventually switch back to blocking my programs from internet access. I appreciate the help, Thank you
