No internet in LAN Windows 10

I don't understand why this is happening. There is internet connection via Wifi but none in the LAN. It keeps saying "Network, No internet access" to both of my conputers running on Windows 10. I tried swapping cables and all but to no avail.

My setup is Modem>Switch>2 Devices via LAN (1. Dedicated ASUS Wireless router 2. Directly connected desktop PC)

Is that an actual modem? With but 1 port on the back?
If so, your setup WILL Not Work.

A modem serves up one and only one IP address, to one and only one device.
Usually, that would be the router.
The router then serves multiple devices, both wired and WiFi.

You seem to have two devices connected to the modem...the router and the PC.
This will not work.

What needs to happen is:

Modem->router->devices, both wired and WiFi

Well I let my ISP figure it out turns out it was just hardware issues. My modem is pretty old about 8 years. Thanks though
