Network card working but no internet

[Dellerati]

Hi I'm new to this site and I'm hoping I can find some answers here. My PCI-e Wifi adapter is working, and I'm able to connect to a wireless access point fine. But when I open my browser and go to google, it will not load. And evetually it says "No network connection."
However, if I plug a different adapter in, everything works perfectly fine.
One weird thing about the first adapter is that sometimes if I refresh the router, it will connect for like five seconds. Then stop working again. The device is fine, and system tray icon for wireless has no warning or disable indication.

Power cycle the modem
unplug the router from ac and modem and wait for the router lights to flash and are ready
Power on the router and connect it to the modem
Go into the router and make sure under WAN (internet) it gets the DNS from the ISP there should be two of them listed. If you see 0.0.0. or 192.168.x.x then the Router is not communicating correctly with the modem.

If you see this the router would need a factory reset and re-run the setup again.
If all looks good but it's the PC that not connecting
